Review on Effect of Swirl Flow in a Concentric Tube Heat Exchanger

Abstract

The objective of this thesis is to investigate the swirl flow behaviour and the laminar convective heat transfer in a circular tube with twisted-tape inserts. The fluid flow and thermal fields are simulated computationally in an effort to characterize their structure. Apart from this, issues like long term performance & detailed economic analysis of heat exchanger has to be studied. To achieve high heat transfer rate in an existing or new heat exchanger while taking care of the increased pumping power.
Keywords: Twisted tapes; pumping power; friction factor; enhancement techniques.
