Over the course of the semester, I have transitioned from a conceptual understanding of thermodynamics to a rigorous, application-based proficiency in modeling complex energy systems. This portfolio, and the evidence contained within it, demonstrates my ability to solve multi-stage engineering problems, analyze system failures, and interpret thermodynamic data with the precision required of a professional engineer.<\/span><\/p>\n<h3 id=\"h.5cpjj7g9sire\" class=\"c0\"><span class=\"c5 c1\">1. Persuasion of Course Objective Mastery<\/span><\/h3>\n<p class=\"c0\"><span class=\"c3 c4 c2\">I am confident that my work throughout this course meets and exceeds the established learning objectives. My learning process was characterized by a commitment to technical writing and a refusal to shy away from complex, multi-component systems. Below is a detailed mapping of my work to the course objectives:<\/span><\/p>\n<ul class=\"c10 lst-kix_4i0as0dvtj05-0 start\">\n<li class=\"c8 li-bullet-0\"><span class=\"c1\">First and Second Laws of Thermodynamics:<\/span><span class=\"c2\">\u00a0My intuitive understanding is demonstrated in the\u00a0<\/span><span class=\"c2\">[Test 1] and [Test 2]\u00a0<\/span><span class=\"c3 c4 c2\">energy balances. I did not simply follow formulas; I performed mass and energy conservation checks at every state point.<\/span><\/li>\n<li class=\"c8 li-bullet-0\"><span class=\"c1\">Gas Turbine Engines (Brayton Cycles):<\/span><span class=\"c2\">\u00a0In\u00a0<\/span><span class=\"c2\">[Test 1]<\/span><span class=\"c3 c4 c2\">, I analyzed a gas turbine using intercooling and regeneration. I successfully demonstrated how intercooling reduces compressor work, which is a core requirement of this objective.<\/span><\/li>\n<li class=\"c8 li-bullet-0\"><span class=\"c1\">Internal Combustion Engines:<\/span><span class=\"c3 c4 c2\">\u00a0Through homework and class discussions, I mastered the analysis of ideal air-standard cycles (Otto and Diesel), focusing on compression ratios and their impact on thermal efficiency.<\/span><\/li>\n<li class=\"c8 li-bullet-0\"><span class=\"c1\">Jet Propulsion Engines:<\/span><span class=\"c2\">\u00a0I applied thermodynamic laws to a Turbojet engine in<\/span><span class=\"c2\">\u00a0[Test 1, Problem 2]. Despite a numerical error in velocity, my setup of the diffuser,\u00a0<\/span><span class=\"c3 c4 c2\">turbine-compressor coupling, and nozzle energy balances proved my ability to model propulsion systems.<\/span><\/li>\n<li class=\"c8 li-bullet-0\"><span class=\"c1\">Rankine Cycles with Regeneration:<\/span><span class=\"c2\">\u00a0My work in\u00a0<\/span><span class=\"c2\">[Test 2] i<\/span><span class=\"c3 c4 c2\">s my most significant evidence for this objective. I modeled an 8-state system including superheating, an open feedwater heater (OFWH), and a closed feedwater heater (CFWH) with a trap.<\/span><\/li>\n<li class=\"c8 li-bullet-0\"><span class=\"c1\">Combined Cycles &amp; Co-generation:<\/span><span class=\"c3 c4 c2\">\u00a0Through class participation and the study of binary vapor cycles, I developed a clear understanding of how topping and bottoming cycles can be merged to push thermal efficiency beyond the limits of a single cycle.<\/span><\/li>\n<li class=\"c8 li-bullet-0\"><span class=\"c1\">Efficiency and Energy Availability:<\/span><span class=\"c2\">\u00a0I consistently calculated thermal efficiency across all artifacts. In my<\/span><span class=\"c2\">\u00a0[Test 2 Reflection]<\/span><span class=\"c3 c4 c2\">, I specifically discussed how the failure of a feedwater heater influences energy availability and boiler heat input ($Q_{in}$).<\/span><\/li>\n<li class=\"c8 li-bullet-0\"><span class=\"c1\">Refrigeration and Heat Pumps:<\/span><span class=\"c3 c4 c2\">\u00a0I demonstrated knowledge of vapor compression cycles by analyzing the cooling effect and COP (Coefficient of Performance) in various homework assignments.<\/span><\/li>\n<li class=\"c8 li-bullet-0\"><span class=\"c1\">Psychrometry and Air-Conditioning:<\/span><span class=\"c2\">\u00a0I mastered the use of the\u00a0<\/span><span class=\"c1\">Psychrometric Chart<\/span><span class=\"c3 c4 c2\">\u00a0to define cooling with dehumidification and heating with humidification, tools that are essential for HVAC design.<\/span><\/li>\n<\/ul>\n<h3 id=\"h.srraqhse0lzu\" class=\"c0\"><span class=\"c5 c1\">2. Reflective Evidence and Self-Assessment<\/span><\/h3>\n<p class=\"c0\"><span class=\"c3 c1\">1) Where is your learning demonstrated in the course?<\/span><\/p>\n<p class=\"c0\"><span class=\"c2\">My learning is most visibly captured in my\u00a0<\/span><span class=\"c2\">[Test 1 Reflection] and [Test 2 Reflection]. These documents go beyond the math; they show my ability to critique my own work. For example, in [Test 1], I identified that a regenerator was ineffecti<\/span><span class=\"c3 c4 c2\">ve because the turbine exit temperature was lower than the compressor exit temperature\u2014a discovery that required a deep conceptual grasp of the Second Law.<\/span><\/p>\n<p class=\"c0\"><span class=\"c3 c1\">2) What areas did you feel you were most successful, or improved the most?<\/span><\/p>\n<p class=\"c0\"><span class=\"c2\">I improved the most in\u00a0<\/span><span class=\"c2\">State Identification. Early in the semester, I struggled to navigate steam and gas tables quickly. By [Test 2],<\/span><span class=\"c3 c4 c2\">\u00a0I was able to fluently move between saturated, superheated, and compressed liquid tables to define eight distinct states within a single problem.<\/span><\/p>\n<p class=\"c0\"><span class=\"c3 c1\">3) How do you see this course\u2019s content intersecting with your field or career?<\/span><\/p>\n<p class=\"c0\"><span class=\"c3 c4 c2\">As an engineer currently involved in thermal applications, the intersection is direct. The ability to calculate mass flow fractions (y and z) is critical for optimizing industrial steam systems. This course provides the &#8220;why&#8221; behind the performance data I see in the field.<\/span><\/p>\n<p class=\"c0\"><span class=\"c3 c1\">4) Have you been able to apply concepts to work or other courses?<\/span><\/p>\n<p class=\"c0\"><span class=\"c2\">Yes. I have already begun apply<\/span><span class=\"c2\">ing energy balance logic to\u00a0<\/span><span class=\"c3 c4 c2\">my professional tasks, specifically when assessing the efficiency of heat exchangers. The systematic &#8220;State 1, State 2&#8230;&#8221; approach learned in MET 350 has made my field reports more organized and technically sound.<\/span><\/p>\n<p class=\"c0\"><span class=\"c3 c1\">5) How, when, where, and why might you use this information in the future?<\/span><\/p>\n<p class=\"c0\"><span class=\"c2\">I will use these skills whenever I am tasked with a<\/span><span class=\"c2\">\u00a0system optimization project.<\/span><span class=\"c3 c4 c2\">\u00a0Whether it is upgrading a cooling tower or justifying the addition of a reheater to a power cycle, I will use the thermodynamic modeling skills from this course to prove the return on investment (ROI).<\/span><\/p>\n<p class=\"c0\"><span class=\"c3 c1\">6) Do you think what you learn is important for your professional career?<\/span><\/p>\n<p class=\"c0\"><span class=\"c3 c4 c2\">Absolutely. Thermodynamics is the bedrock of mechanical engineering. Understanding the limits of efficiency (the Carnot limit) prevents wasted time on physically impossible designs.<\/span><\/p>\n<p class=\"c0\"><span class=\"c3 c1\">7) Where do you think you will be using everything you learned?<\/span><\/p>\n<p class=\"c0\"><span class=\"c2\">I will use these tools in\u00a0<\/span><span class=\"c3 c4 c2\">energy audits, power plant design, and HVAC system assessments. These concepts are universal to any industry that moves heat or produces work.<\/span><\/p>\n<p class=\"c0\"><span class=\"c3 c1\">8) If you were starting this class again, what advice would you give yourself?<\/span><\/p>\n<p class=\"c0\"><span class=\"c2\">I would tell myself:\u00a0<\/span><span class=\"c2\">&#8220;Double-check your nozzle calculations.&#8221;\u00a0<\/span><span class=\"c2\">My experience with the negative thrust result in<\/span><span class=\"c2\">\u00a0[Test 1]<\/span><span class=\"c3 c4 c2\">\u00a0taught me that numerical precision is just as important as conceptual logic. I would also recommend setting up a &#8220;unit verification&#8221; column for every problem.<\/span><\/p>\n<hr \/>\n<h3 id=\"h.twlemdkmu3p8\" class=\"c0\"><span class=\"c1 c5\">3. Engineering Growth and Mindset<\/span><\/h3>\n<p class=\"c0\"><span class=\"c3 c1\">1) How have you improved as an engineer?<\/span><\/p>\n<p class=\"c0\"><span class=\"c2\">I have improved<\/span><span class=\"c2\">\u00a0in Technical Rigor. Dr. Ayala&#8217;s focus on technical writing and organized diagrams (as seen in my [Test 1 Diagrams]) forced me to slow down and document my assumptions. This discipline is what separates a st<\/span><span class=\"c3 c4 c2\">udent from a professional.<\/span><\/p>\n<p class=\"c0\"><span class=\"c3 c1\">2) What was your biggest accomplishment?<\/span><\/p>\n<p class=\"c0\"><span class=\"c2\">My biggest accomplishment was\u00a0<\/span><span class=\"c2\">the [Test 2 Failure Analysis]. Modeling<\/span><span class=\"c3 c4 c2\">\u00a0the system when the closed feedwater heater failed required me to rethink the entire mass balance. Successfully showing how the efficiency dropped and how the boiler had to work harder was a moment of true engineering insight.<\/span><\/p>\n<p class=\"c0\"><span class=\"c1 c3\">3) What skills did you master?<\/span><\/p>\n<p class=\"c0\"><span class=\"c3 c4 c2\">I mastered Psychrometric Charting and Isentropic Property Modeling. These are reflected in my [Homework Assignments] and [Test 2], where I used isentropic efficiencies to account for real-world losses in pumps and turbines.<\/span><\/p>\n<p class=\"c0\"><span class=\"c3 c1\">4) What are your strengths and weaknesses?<\/span><\/p>\n<ul class=\"c10 lst-kix_nzleokxr7ku3-0 start\">\n<li class=\"c8 li-bullet-0\"><span class=\"c1\">Strength:<\/span><span class=\"c2\">\u00a0<\/span><span class=\"c1\">Visualization.<\/span><span class=\"c2\">\u00a0My T-s diagrams (see<\/span><span class=\"c2\">\u00a0[Test 2, Page 1])\u00a0<\/span><span class=\"c3 c4 c2\">are clear and technically accurate, which helps me avoid &#8220;lost states.&#8221;<\/span><\/li>\n<li class=\"c8 li-bullet-0\"><span class=\"c1\">Weakness:<\/span><span class=\"c2\">\u00a0<\/span><span class=\"c1\">Numerical Transcription.<\/span><span class=\"c2\">\u00a0In<\/span><span class=\"c2\">\u00a0[Test 1],<\/span><span class=\"c3 c4 c2\">\u00a0a transcription error from a gas table led to an incorrect final result. I am addressing this by using a more structured &#8220;Input Data&#8221; section in my reports.<\/span><\/li>\n<\/ul>\n<p class=\"c0\"><span class=\"c3 c1\">5) How have your assumptions changed?<\/span><\/p>\n<p class=\"c0\"><span class=\"c2\">Before this course, I thought efficiency was simply a matter of &#8220;better parts.&#8221; Now, I understand that efficie<\/span><span class=\"c3 c4 c2\">ncy is a product of Cycle Architecture. I used to assume that adding a component always helped; I now know that if the temperatures don&#8217;t align (as in my Test 1 Regenerator analysis), the component can actually be useless. This shift from &#8220;hardware-focused&#8221; to &#8220;system-focused&#8221; thinking is my most valuable takeaway.<\/span><\/p>\n<p class=\"c0\"><span class=\"c3 c4 c2\">In conclusion, the work archived in this ePortfolio represents a significant leap in my engineering capabilities. I have met all course objectives and am prepared to apply these thermal applications to solve real-world engineering challenges.<\/span><\/p>\n<p class=\"c0\"><span class=\"c3 c4 c2\">Sincerely,<\/span><\/p>\n<p class=\"c0\"><span class=\"c3 c1\">Joshua Ware<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Subject: MET 350 Final Reflective Portfolio Letter To:\u00a0Dr. Orlando Ayala and the Engineering Assessment Committee From:\u00a0Joshua Ware Date:\u00a0May 6, 2026 Dear Dr. Ayala and members of the Assessment Committee, This letter serves as a comprehensive reflection on my academic journey&#8230; <a class=\"more-link\" href=\"https:\/\/sites.wp.odu.edu\/engineering\/\">Continue Reading &rarr;<\/a><\/p>\n","protected":false},"author":32430,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"_links":{"self":[{"href":"https:\/\/sites.wp.odu.edu\/engineering\/wp-json\/wp\/v2\/pages\/4"}],"collection":[{"href":"https:\/\/sites.wp.odu.edu\/engineering\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/sites.wp.odu.edu\/engineering\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/sites.wp.odu.edu\/engineering\/wp-json\/wp\/v2\/users\/32430"}],"replies":[{"embeddable":true,"href":"https:\/\/sites.wp.odu.edu\/engineering\/wp-json\/wp\/v2\/comments?post=4"}],"version-history":[{"count":5,"href":"https:\/\/sites.wp.odu.edu\/engineering\/wp-json\/wp\/v2\/pages\/4\/revisions"}],"predecessor-version":[{"id":93,"href":"https:\/\/sites.wp.odu.edu\/engineering\/wp-json\/wp\/v2\/pages\/4\/revisions\/93"}],"wp:attachment":[{"href":"https:\/\/sites.wp.odu.edu\/engineering\/wp-json\/wp\/v2\/media?parent=4"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
