Applied Thermodynamics, Heat Transfer, Fluid Mechanics

Learning outcomes
The aim of the course is to integrate the fundamentals of applied thermodynamics, heat transfer and fluid dynamics in order to provide students with the necessary tools for the optimal design of thermal systems operating in the production, transport and final uses of energy. This knowledge completes the previous engineering education and increases the understanding of both thermal energy systems and their components deepening the issues related to the production, conversion of energy and providing techniques for the environmental impact assessment. Students will be aware of the multidisciplinary context of engineering with particular focus on the issues related to the conversion, transmission, final use of energy and to the design of fluid machines and energy systems
In order to apply the acquired knowledge, students should be able to face complex design problems and to manage innovation and development of new products and/or new technological processes. In particular, they must be able, in the design phase, to optimize systems for the exchange and the conversion of thermal energy. The main skills acquired in the course are: 1. ability to perform first and second law energy analyses on components and systems with advanced thermodynamics analysis tools; 2.ability to perform first and second law analyses on heat exchangers and heat exchangers networks aimed at process integration for saving energy and costs; 3.ability to perform optimal choices in the design of thermal systems for the production, the transport and the final use of energy aimed at saving energy and costs while minimizing environmental impact
The ability of solving numerical problems, together with the awareness of their knowledge, will improve the judgement autonomy of students, their communications skills and their learning ability

Class lectures contents (48 hours): First Law, Second Law, Property Relations, Basic Relations for Pure Substannces, Multicomponent Systems, Reacting Mixtures, Exergy, Physical Exergy, Exergy Balance, Control Volume Exergy Balance, Chemical Exergy, Exergy Destruction and Exergy Loss, Exergetic Efficiency, Improving Thermodynamic Effectiveness, Heat Exchangers, LMTD, Epsilon-NTU method, Economic Analysis, Prnciples of Economic Evaluation, Levelization, Fundamentals of Thermoeconomics, Thermoeconomic Variables, Thermoeconomic Evaluation, Costing Considerations, Introduction to Optimization, Analytical and Numerical Optimization Techniques, Cost-optimal Exergetic Efficiency, Thermoeconomic Optimization of Complex Systems, Pinch Analysis, Composite Curve and Process Pinch, Maximum Energy Recovery, Grand Composite Curve, Cost-optimal Hexchanger Network Design. Class exercises (24 hours): numerical exercises related to technological applications learned during the course.

Development of the examination
The assessment of the learning level consists of a test divided into two parts: in the first part, the student must solve two numerical exercises related to technological applications that have been discussed in class. In the second part, the student has to answer 2 questions on theoretical topics chosen from among those discussed in class. The time available for the test as a whole is 120 minutes.

To successfully pass the exam, the student must demonstrate, through the tests described above, to have assimilated the concepts contained in the syllabus and to be able to properly solve numerical exercises related to technological applications learned during the course.

The numerical exercises are evaluated with a maximum total score of 60 points out of 100 (each exercise is given a maximum score of 30 points, with a total of 60). The 2 theoretical questions are evaluated with a maximum total score of 40 points out of 100 (each question is given a maximum score of 20)

The vote in hundredths, obtained by adding the vote gained in any exercise and theoretical question, is converted in thirtyeths. The “Lode“ is given to those who, in addition to achieving the maximum score on the test, demonstrate to master very well the subject.
