| DESCRIPTION | This study-unit covers in some detail the three modes of heat transfer, that is Conduction, Convection and Radiation. It highlights the various thermal properties of materials and their physical significance. Problem solving techniques are introduced based on the principle of energy conservation. The following topics are covered in Heat Transfer by Conduction: - Fourier Law of conduction; - Heat Energy Equation in Cartesian, Cylindrical and Spherical coordinate systems; - 1D steady state conduction with and without heat generation; - 1D transient conduction. The following topics are covered in Heat Transfer by Convection: - Hydrodynamic and thermodynamic boundary layers; - Heat transfer in internal flows such as flow in pipes; - Heat transfer in external flows such as flow over surfaces; - Correlations used in heat transfer by Natural and Forced convection. The following topics are covered in Heat Transfer by Radiation: - Introduce the concepts of Black and Gray bodies; - Planck Distribution; - Stefan Boltzmann Law; - Radiation exchange between surfaces (both black and gray); - Environmental radiation. The study-unit introduces the theory behind extended Surfaces or Fins. Heat Exchangers analysis techniques, including LMTD and NTU methods, will also be introduced together with the various types and constructions commonly encountered in engineering. Study-unit Aims: This study-unit introduces the phenomenon of heat transfer. The objective of this study-unit is to provide students with fundamental knowledge and tools to analyse heat transfer in complex systems. Learning Outcomes: 1. Knowledge & Understanding: By the end of the study-unit the student will be able to: - Distinguish between the three modes of heat transfer (conduction, convection and radiation); - Explain differences between forced and natural convection; - Analyse heat transfer processes in complex systems using analytical, experimental and numerical techniques; - Interpret measurement data from practical experiments involving heat transfer processes. 2. Skills: By the end of the study-unit the student will be able to: - Apply the lumped capacity and finite difference methods to analyse multi-mode heat transfer in complex systems; - Design and analyse heat exchangers using the LMTD and NTU methods; - Investigate radiation exchange between black and gray bodies.
