Amplifying the Heat Transfer is Double Pipe Heat Exchanger with Various Inserts and Nanofluids – Review

Abstract

Techniques to enhance heat transfer rates while at the same time reducing heat exchanger size-and-cost. Passive heattransfer strategies among them have been found to be extremely effective, and the technique of using inserts has gained considerable importance in terms of enhancing flow turbulence. Comprehensive review on experiments and numerical investigations and different insert designs, and tube geometries, are presented in the current work. These technologies have targeted improving critical performance parameters of heat exchangers. After reading about past methods designed to increase turmoil and system effectiveness, tape inserts are presented up as according to a highly effective description. They have attracted considerable attention and are used extensively to enhance the performance of heat exchangers, particularly with Nanofluids. Studies also show that inserts are very efficient both in laminar-andturbulent flow regimes and are thus suited for application with Nanofluids to further improve heat transfer.
