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

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.


Module Content



Further treatment of Laws of Thermodynamics, principally the second law, and its corollaries.  Irreversibility.   Perfect gases and perfect gas processes.

Reciprocating Engine Cycles:

Analysis of air standard cycles for reciprocating engines: Otto, Diesel, dual.  Cycle efficiency.

Gas Turbine Cycles:


Cycles of steady flow processes - gas turbine cycle, jet engine.  Thermal efficiency, net specific work output and work ratio.



Mixtures of gases, and of gases (and vapours):


Gibbs-Dalton Law, volumetric and gravimetric analysis, mean properties. 


Gases in equilibrium with a condensed phase, application of the First Law.
