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.

*Type*	*Hours*	*Description*
Workload	Full-time hours per semester
Lecture	24	Two lectures per week
Tutorial	12	One tutorial per week
Directed learning	20	The module content will be delivered through a variety of lectures, tutorials, and a challenge-based learning assignment. It is expected that industry will be involved in the delivery of this learning activity – for example, a case study from industry could be used as the basis for a project in conjunction with the other new second year module, i.e. MM2XX Electrical power and electromechanical systems.
