Description Thermodynamics II follows on directly from MM204, i.e. from the First law of Thermodynamics to Entropy, the Second Law, and Exergy Analysis. The module focuses on the theory and application of thermodynamic principles to study engineering processes and/or systems. The students will use the thermodynamic properties of entropy and exergy to quantify and improve the thermodynamic efficiency of engineering systems. The principles of psychrometry are introduced, and are used to understand the thermodynamics of air/water vapour mixtures for HVAC applications. Chemical energy, the heating values of fuels, and principles of the combustion processes are also presented. | |||||||||||||||||||||||||||||||||||||
Learning Outcomes 1. Explain the concept of irreversibilities, using the property entropy. 2. Derive the entropy balance equation for common system models: e.g. ideal gas and incompressible fluid. 3. Understand the concept of exergy and the dead state; apply exergy analysis to analyse thermodynamic system efficiency and irreversibilities. 4. Apply the principles of pyschrometry to analyse air and water vapour mixture systems 5. Understand the principles of combustion, and calculate the stoichiometric coefficients of the combustion process. | |||||||||||||||||||||||||||||||||||||
