The first part of the course is an introduction to engineering thermodynamics with emphasis on its rigorous general foundations. After a concise summary of the definitions of energy, entropy and availability, several applications of energy and entropy balances are discussed including bulk-flow interactions and modelling of energy-conversion devices (pumps, compressors, turbines, heat exchangers) and the simplest energy conversion systems; steam tables; moist air; exergy; cost allocation of energy consuption in cogeneration plants.
The second part of the course is an introduction to heat transfer covering mainly conduction (Fourier law; heat diffusion equation and its solutions in simple geometries with fixed and convective boundary conditions; lumped capacitance method and Heisler diagrams for unsteady problems) and radiation(blackbody radiation; gray surfaces; radiation exchange among gray surfaces)
