Numerical Heat Transfer Analysis of Flowing Fluid through a Circular Tube with Helical Twisted Strip Inserts

Enhancing Heat Transfer in a Circular Pipe with Helical Strip Inserts

Abstract

Heat exchanger application in industrial as well as application in engineering is quite popular. The need is to improve heat transfer rate, reduce pressure drop with respect to long term performance aspect of equipment. The present work will be focused on heat transfer enhancement of heat exchanger using helical strip in circular pipe with working fluid as water. Circular pipe helical strip geometry is not reported yet in the open literature. This geometry helps to generates swirl motion of fluid flow and disturbs the boundary layer to increase the effective surface area, residence time, reduce pressure drop and increase heat transfer coefficient.
