Evaluating the Performance of Concentric Tube Heat Exchanger With And Without Dimples By Using Cfd Analysis

Abstract

A heat exchanger is a device that is used to transfer thermal energy (enthalpy) between two or more fluids, between a solid surface and a fluid, or between solid particulates and a fluid, at distinctive temperatures and in thermal contact. Heat exchangers are vital engineering devices in many process industries since the efficiency and economy of the process largely depend on the performance of the heat exchangers. In present work, first concentric tube exchanger is designed and then dimple tube concentric heat exchanger is designed in solid works 2016 design software. CFD analysis is carried out in solid works flow simulation by using three different materials such as austenitic stainless steel, hastelloy and titanium. And efficient heat transfer rate for the given materials is studied in both types of heat exchangers.
