A wide range of studies was conducted to increase the heat transfer rate and reduce the size
and cost of shell and tube heat exchangers (STHE). The paper's contributions lie in its ability …

Vertical shell and tube heat exchangers play a critical role in many industrial processes, and
their importance lies in their high heat transfer efficiency, versatility, compact size, easy …

This study proposes a novel active method, the electromagnetic vibration method, to
augment heat transfer in a heated copper tube. To that end, a stretched wire turbulator with a …

Shell and helically coiled tube heat exchangers composed from curved tubes inside a shell
which are often preferred devices particularly in several applications like refrigeration, heat …

In this paper, simultaneous use of active and passive methods for enhancing the thermal
performance of a double-tube heat exchanger was investigated. This was done by injecting …

In this numerical study, an attempt has been made to improve the thermal performance of
the flat-plate solar collector (FPSC) by inducing the swirl flow inside the tube by the …

Abstract Shell and Helically Coiled Tube Heat Exchangers (SHCTHEXs) are utilized in
energy conversion applications in industry and in various engineering systems. They are …

The economic and operational constraints are the most important ones when it comes to
decide to use any performance enhancement method. In this paper, the effect of Al 2 O 3 …

At present study, thermal performance of a double tube heat exchanger due to stream of
air/water two phase flow through inner tube is experimentally studied. Air and hot water were …

The effect of circumferential corrugations on the thermo-exergetic and economic efficiency of
the helical tube is numerically studied for the first time. In the field of heat transfer …
