ABSTRACT
This chapter considers heat transfer by conduction through solids and the use of Fourier's law. It looks at convection and heat transfer through solids, composites, cylinders and pipes. The in-depth study of heat transfer requires the use of some relatively sophisticated mathematics, involving partial differential equations that are considered beyond this introductory text. Technically, only conduction and radiation are true heat transfer processes, because both of these transmission methods depend totally and utterly on a temperature difference being present. Briefly explain the nature of heat transfer by: conduction, convection, radiation. The flow of heat through a composite wall and the resistance to this heat flow by each of the materials is similar to the resistance to current flow set up in an electric circuit. Heat transfer by convection consists of two mechanisms. Convection heat transfer may be classified according to the nature of the flow.
