WM215-15 Engineering Thermofluids
Introductory description
The overall module aim is to develop the abilities to understand, model and analyse heat transfer and fluid flow and apply these to engineering systems.
Module aims
The module incorporates two components of thermal fluid sciences - heat transfer engineering and fluid mechanics.
The heat transfer component will cover different heat transfer modes, formulating them in order to analyse steady-state and transient behaviour of the bodies subjected to thermal gradients.
Thermal resistance approach, heat capacity and the lumped mass approximation are dealt with by both analytical and numerical methods.
The fluid mechanics component includes the flow properties, Newtonian and non-Newtonian fluids, the principles of conservation of mass and momentum, laminar and turbulent flows, pipe flows, flow resistance, friction and losses in pipes, ducts and fittings for case of fluids in motion.
