Objectives

To study the thermodynamic processes of multi-component mixing with and without chemical reaction in order to know how to characterize humid air (psychrometry) and combustion treatment processes and, based on the knowledge acquired in Thermodynamics I, to evaluate the energy and environmental performance of real energy conversion systems (eg internal combustion engines, gas turbines, steam plants, refrigeration systems). In this course, reference is also made to diagnostic techniques used for the experimental characterization of humid air and combustion processes.

Program

Part II - Combustion 2.1 Introduction: Fuels. Types of flames 2.2 Chemical reactions. Equivalence ratio. Stoichiometry
2.3 Thermochemistry. Enthalpy of formation and reaction, calorific power 2.4 Energy balance to combustion processes
2.5, Adiabatic combustion temperature.
Part III - Advanced Thermodynamic Cycles 3.1 Steam Cycles. Combined cycles and Cogeneration 3.2 Organic Cycles., energy sources for organic cycles: Biomass, Geothermal, industrial thermal effluents. Solar energy 3.2 Gas Turbine with intermediate heating and cooling and regeneration. Aeronautical and industrial applications. 3.3Refrigeration Machines and Heat Pumps. Steam compression and absorption cycles

Teaching Methodologies

4 mini tests performed during the class period, contributing 40% to the final grade. The final exam contributes 60% of the final grade. In the event that the final grade exceeds 17 values, the student can choose between taking an oral exam or staying with the grade of 17 values
