Unit Description and General Aims

This unit will serve as an advanced course in thermodynamics with a focus on heat transfer. The prerequisites for this unit are the undergraduate knowledge in thermodynamics and fluid mechanics, specifically Thermal Fluids Engineering or their equivalents. This unit covers problems of heat transfer in great depth and complexity and incorporates many topics; analysis is given greater emphasis than the use of correlations. Furthermore topics on thermodynamics and heat transfer, heat exchanger design, heat conduction problems, convective heat transfer, forced convection and radiative heat transfer are discussed.

This unit is a core subject directed at students having a strong interest in Mechanical Engineering and the application of Thermodynamics and Heat Transfer in solving both theoretical and practical industrial problems..
