Economic reasons (material and energy saving) leads to make efforts for making more
efficient heat exchange. The heat transfer enhancement techniques are widely used in many …

With the growing need for more energy, it is imperative to design efficient heat exchangers
that are simpler, cheaper to manufacture, have higher heat transfer rates, and low in …

Growing need to develop and improve the effectiveness of heat exchangers has led to a
broad range of investigations for increasing heat transfer rate along with decreasing the size …

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 …

In this paper, the Response Surface Methodology (RSM) and two phase mixture model are
proposed to investigate the sensitivity analysis of heat transfer and heat exchanger …

In this study, 3-D numerical simulations were carried out to analyse the influence of
geometrical parameters for eight spirally inner corrugated tubes at turbulent flow (R e= 25× …

A novel twisted annulus between two counter-twisted oval tubes is proposed for a double-
tube heat exchanger. The oval tubes of the annuli have same twist pitch, but twist with …

Heat exchangers are thermal systems which are used extensively, have a major role in
energy conservation aspect and preventing global warming. This paper is based on reviews …

In this paper, the design and thermo-hydraulic performance of a double pipe heat exchanger
with helical baffles in the annulus side, are investigated numerically. Three-dimensional …

With the increasing high heat transfer requirement of modern industry, it is still an important
issue that how to improve the thermal performance of heat exchangers efficiently. The …
