Contents a) Thermodynamics Fundamentals

Fundamentals of thermodynamic e.g. open and closed systems, steadystate processing, state of matter, heat, molecular agitations, ideal gases, real gases; thermodynamic properties (internal energy, enthalpy, free energy, free enthalpy, entropy, specific heat); first and second law of thermodynamics for a closed system; thermodynamic relations (Gibbs equations, Maxwell's equations, characteristic functions, general expressions of S, U and H, general relationship between Cp and Cv); thermodynamic equilibrium phases (chemical potentials); state equations applied to pure fluids (state equation of ideal gases); thermodynamics of mixtures (mixture of ideal gases, ideal solutions); first law of thermodynamics for open systems (mass and energy balance); second law of thermodynamics for open systems (entropy balance sheet); exergy analysis (generation of entropy and exergy destruction, application to steady flows and closed systems); gas turbine (operating principle, Brayton cycle, inverted Brayton cycle), steam turbine (block diagram, Rankine cycles); engines; refrigeration machines, single-stage and two-stage vapor compression (schematic diagrams, thermodynamic cycles in PH and TS diagrams, two-stage compression and expansion); cryogenic thermodynamic processes; liquefaction of air (Linde and Claude cycles); production of dry ice.
