Investigation of Heat Transfer Rates on Shell and Tube Heat Exchanger by Numerical Modelling via CFD Analysis

Abstract

A shell and tube heat exchanger design with respect to the total heat transfer rate and temperature profile has been invstigated by numerical modelling. The HE comprises of a single tube and has been resolved by the two equation models namely, the k epsilon and k omega. The low RMS residual levels calculated showed that the convergence is better in the k omega. The differences in the heat transfer rates noted are likely due to the low number of iterations on the flow and heat transfer helps explain the selection of an appropriate model i.e. k omega.
