Module Overview

The topic of thermodynamics develops that started in Level 1. It covers the importance of the 2nd law in understanding cycles and processes; the theoretical efficiency of common engine cycles; the analysis of air-vapour mixtures in air-conditioning and cooling towers; simple combustion chemical analysis and prediction of the thermal gain through combustion.  This module is taken by Mechanical & Aerospace Engineering students
Prerequisites/Co-requisites
Pass HE1, or equivalent.
Module Aims

To develop and apply prior understanding of the first law and develop and apply understanding of the second law, to perfect-gas thermodynamic processes and internal combustion gas power cycles - reciprocating and non-reciprocating  - mixtures of gases, and combustion.

 

 
Learning Outcomes

Upon successful completion of the module, you will  be able to:

 

  • apply thermodynamic principles to various reciprocating engine cycles, gas turbine cycles and reversed cycles

     

  • understand consequences of flow friction and process irreversibility

     

  • calculate entropy changes in a system and predict system thermal efficiency

     

  • apply thermodynamic principles to properties of gas mixtures

     

  • apply the Gibbs-Dalton laws and calculate the changes in internal energy and enthalpy

     

  • analyse combustion of gases processes and predict heat energy gains.
