Water flowing at a rate of 0.723 / enters the inside of a countercurrent, double-pipe heat exchanger at 300.K and is heated by an oil stream that enters at 385 at a rate of. 3.2 / . The heat capacity of the oil is 1.89 / , and the average heat capacity of the water of the temperature range of interest is 4.192 / .
The basic thermal design theory for recuperators is presented in Chapter 3, advanced design theory for recuperators in Chapter 4, and thermal design theory for regenerators in Chapter 5. Pressure drop analysis is presented in Chapter 6.
A heat exchanger is a component that allows the transfer of heat from one fluid (liquid or gas) to another fluid. Reasons for heat transfer include the following:
Heat transfer theory. Heat can be transferred by three methods. Radiation – Energy is transferred by electromag netic radiation. One example is the heating of the earth by the sun. Conduction – Energy is transferred between solids or stationary fluids by the movement of atoms or molecules.
To introduce and apply basic heat exchanger design concepts to the solution of industrial heat exchanger problems. Primary emphasis is placed on fundamental concepts and applications. Also, more emphasis is placed on analysis and less on empiricism.
Heat Exchanger Design. John Richard Thome. 1er mars 2008 Heat exchanger goal : get energy from one fluid mass to another. Simple or composite wall of some kind divides the two flows and provides an element of thermal resistance between them. Figure 3.1 Heat exchange. Exception : Direct-contact form of heat exchanger. Steam is bubbled into water.
Abstract. This chapter provides an overview of how different heat exchanger types, prob-lems, and networks are analyzed. Heat exchangers are categorized by shape, flow arrangement, area to volume ratio, and channel size. The problem type depends on what information is available and what is sought.
