Skills and learning outcomes
Description of contents: programme
This is a basic course of thermodynamics and an introduction to heat transfer. The program can be divided in 2 main blocks, one about thermodynamics and another about heat transfer. FIRST PART (THERMODYNAMICS AND CYCLES): - Review of previous concepts of thermodynamics acquired by the student, thermodynamic properties, T-s diagram of water, incompressible liquid and ideal gas models. - Mass, energy and entropy balance for closed systems. - Mass, energy and entropy balance for open systems. - Equipments under steady state: nozzles, diffusers, pumps, compressors, turbines, open and closed heat exchangers, and valves. - Thermal engines. Carnot cycle. - Rankine cycle. - Brayton cycle. - Internal combustion engines. - Inverse Carnot cycle. Refrigeration cycle. SECOND PART (HEAT TRANSFER): - Introduction to heat transfer: Fourier's Law, Newton's Law, Stefan-Boltzmann's Law. - One-dimensional steady state conduction with and without heat generation. Plane wall, cyclindrical and spherical geometries. Thermal resistances. - Transient conduction. - Fins: formulation, design and performance analysis. Finned surfaces.
Learning activities and methodology
The teaching methodology will include: (1) Combined classes where the knowledge that students must acquire will be presented and problems will be solved in relation to the knowledge that will be presented. To facilitate their development, students will receive class notes (presentations, problem statements and exams from previous years) and will have basic reference texts that allow them to complete and delve into those topics in which they are most interested. (2) Resolution of exercises by the student that will serve to self-assess their knowledge and acquire the necessary skills. (3) Development of practical works. Preparation of reports presenting the results obtained in the laboratory and/or through computer software. The student's ability to present the results clearly and concisely, as well as their discussion, will be assessed.
