CFD Analysis of Shell and Tube Heat Exchanger with Segmental Baffles

Abstract

Numerical investigation has been done for single pass shell and tube heat exchanger with segmental baffles.Heat transfer and flow pattern are numerically studied by varying number of baffles.Standard k-e model is used for solving the above problem.Numerical simulation has been done for three different cases of baffle spacing with square bundle of tubes.Numerical solutions are obtained by solving 3D continuity,momentum,energy and turbulence(k-e) equations using commercial solver CFD.To analyse the phenomenon,number of baffles is taken as varying parameter; other parameters like velocity,temperature,pressure and baffle cut are kept constant.Results obtained from numerical solution are analysed extensively to get the effect of number of baffles on heat transfer rate and pressure drop on shell side.
