This module is not approved as a discovery module
Objectives
On completion of this module, students should be able to:1. understand the fundamental concepts of incompressible fluid fluid flow in two-dimensions, with consideration of both ideal (inviscid) and real (viscous) flow.
2. analyse ideal and viscous incompressible fluid flow in two-dimensions using the continuum concepts of conservation of mass, momentum and energy.
3. understand and analyse incompressible viscous flow with application to internal flows such as pipes, pipe networks, parallel plates, fluid film bearings and dampers.
4. understand and analyse incompressible viscous flow with application to external flows such as flat plates, cylinders, spheres, airfoils and automobiles.
5. understand the fundamental concepts of heat transfer which include conduction, convection and radiation.
6. understand how to analyse practical heat transfer problems and have an appreciation of practical include heat exchangers
7. understand the fundamental concepts of combustion: fuels, chemical equations, stoichiometry; chemical reaction schemes, rate of reaction, equilibrium, adiabatic flame temperature for constant pressure and volume, pollutant generation mechanisms
