introduce fluid mechanics of real incompressible internal and external flows (following on from frictionless flows) including the basics of boundary layer concept, friction in flow, friction drag, flow separation, form drag and lift, basic mechanics of flying and sailing. This is followed by an introduction to 2 and 3 dimensional conservation equations including Navier-Stokes;
introduce the various ideal thermodynamic cycles that form the basis for power generation, heat pumping and refrigeration. It will also emphasise the difference between the actual and ideal cycles and methods of enhancing the performance of actual cycles.
The module will also introduce fuels, including biofuels and the basic chemistry of combustionl, adiabatic flame temperature calculation and IC Engines performance.
