MODELING OF A VERTICAL SHELL-AND-TUBE HEAT EXCHANGER

Abstract

The shell and tube heat exchanger has been commonly used in the industry. It is important to know the dynamic behavior of the heat exchanger in order to predict how the system will respond to a change in flow rate, temperature, pressure, etc…. Modeling and simulation of the dynamic behavior of a horizontal shell-and-tube heat exchanger are presented in the literature. In this paper, a dynamic modeling of a vertical shell-and-tube heat exchanger is presented. The hot fluid is steam and the cold fluid is water. The objective of this model is to predict steam pressure and level of the condensate water in the heat exchanger. The simulation results of steam pressure and level of condensate water agree well with those of experimental data.
