Heat transfer takes place between two fluids in a heat exchanger either directly or indirectly. Many industrial applications such as power plants, process industry, refrigerators and air-conditioners, automobiles and space vehicles use heat exchangers. The heat transfer priniciples discussed in previous chapters are used in designing a heat exchanger. The design and selection of heat exchangers is discussed in this chapter.
The transfer of thermal energy between fluids is one of the most important and frequently used processes in engineering.
The transfer of heat is usually accomplished by means of a device known as a heat exchanger.
Common applications of heat exchangers is the power plants with boilers, fan ...
