Numerical Simulation of Shell and Tube Heat Exchanger Based on Fluent

Abstract

In this paper, the classical shell-and-tube heat exchanger is taken as the research object, and the numerical simulation of the heat exchanger is carried out by using Fluent software. The nephogram of temperature field, velocity field and pressure field on the shell side of the fixed tube-and-plate heat exchanger with different baffle spacing is obtained. The variation law of fluid flow and heat transfer coefficient on the shell side of the heat exchanger with different baffle spacing is analyzed. the ratio of convective heat transfer coefficient to the third power of pressure drop pis used as the comprehensive performance evaluation index of the heat exchanger, which has a certain reference for evaluating the comprehensive performance of heat exchanger under different baffle spacing.
