Heat transfer analysis of double tube heat exchanger with helical inserts

Improving heat exchangers thermal efficiency marks materials used, the energy obtained and cost savings directly. The improvement of heat exchange will also considerably increase heat efficiency and the economical nature of design and operation in applications requiring thermal transfer processes. Because of their small diameters, double tube heat exchangers are mostly suited for high temperature and high-pressure applications. They are inexpensive, but the amount of way they distribute to the other forms is relatively high. Numerous techniques were designed to achieve the necessary heat transfer rate at an economical pumping capability within the specified design and duration of the heat exchanger. The most popular and efficient techniques for heat exchangers to improve are helical inserts. Helical inserts. This article would investigate the performance of an ANSYS CFX tool for double tube heat exchangers with helical insert. A comparative analysis will be carried out in comparison to the heat exchanger without helical inserts for the heat flux and temperature distribution along the pipe. (c) 2020 Elsevier Ltd.
