Abstract

Shell and tube heat exchanger is the most common type heat exchanger widely use in oil refinery and other large chemical process, because it suits high pressure application. The process in solving simulation consists of modeling and meshing the basic geometry of shell and tube heat exchanger using CFD package ANSYS 15.0. The objective of the paper is design of shell and tube heat exchanger with helical baffle and study the flow, pressure and temperature field inside the shell using ANSYS software tools. In this present work, the heat exchanger contains 9 tubes 600 mm in length and shell diameter 76.1595 mm. The helix angle of helical baffle will be varied from 00 to 200. In simulation will show how the pressure varies in shell due to different helix angle and flow rate. The flow pattern in the shell side of the heat exchanger with continuous helical baffles was forced to be rotational and helical due to the geometry of the continuous helical baffles, which results in a significant increase in heat transfer coefficient per unit pressure drop in the heat exchanger. The quality of the solution has proved that CFD is effective to predict the behavior and performance of heat exchanger.
