Abstract

This project is mainly focusing on designing one type of a heat exchanger which is shell and tube heat exchanger with single segmental baffle. The process in solving simulation consists of modelling and meshing the basic geometry of shell and tube heat exchanger using CFD package ANSYS 16.0. The objective of the project is to perform the CFD analysis on behaviour of flow, investigate the effect of several number of baffle configuration and determine the heat transfer performance inside the shell using ANSYS software tools. Many considerations were taken to design this heat exchanger. The heat exchanger contains 7 tubes of 184 mm long and a shell with diameter of 50 mm. The baffle segment of segmental baffle varies from 2 to 4. Results show how the pressure, temperature and velocity variations depending on number of baffle segment. The flow behaviour in the shell side of the heat exchanger with single segmental baffles was forced to be zigzag manner due to the geometry of the segmental baffles, which results in a significant increase in heat transfer coefficient per unit pressure drop in the heat exchanger. The results obtained can be used to analyse which baffle number is better. Based on the overall calculated value in shell-side of the shell and tube heat exchanger in simulation, 4 baffle segmental number has the highest value of heat transfer rate at 294.24kW, pressure drop at 60.61kPa and overall heat transfer coefficient 2994.35
