A shell and tube heat exchanger is a popular class of heat exchanger designs. It consists of a number of tubes mounted inside a cylindrical shell. One fluid flows inside the tubes and the other through the shell. While flowing they exchange the heats where the cold fluid gains the heat from the hot fluid. […]
Heat exchangers are devices that transfer heat between fluids without mixing or blending them. The fluids are separated by a wall that has high thermal conductivity. The thickness of the wall is designed to prevent the mixing of the fluids or the possibility of direct contact between them. Included in the process is a working […]
