Numerical study of the dynamic and thermal field of a flow in a shell and tube heat exchanger
Main Article Content
Abstract
In order to gain an understanding of the mechanism of thermal performance increase in the shell side, a shell and tube heat exchanger is proposed in this study. Numerical investigations of the shell side fluid flow and heat transfer are performed using CFD Fluent software based on the 
model. The profiles and axial velocity fields, as well as the profiles and temperature distribution at the heat exchanger level were obtained for the whole geometry. The speed increases by 12 % of the reference speed in the shell.
