Journal ArticleDOI
Enhancement of heat transfer in a rectangular channel with perforated baffles
TL;DR: In this article, a perforated baffle having a row of four holes placed at three different positions was investigated and three values were taken for the PAR and which are 0.190, 0.425 and 0.660, respectively.
Journal ArticleDOI
Hydro-thermal shell-side performance evaluation of a shell and tube heat exchanger under different baffle arrangement and orientation
TL;DR: In this article, a three-dimensional numerical simulation of turbulent fluid flow and heat transfer in the shell side of a shell and tube heat exchanger (STHE) has been investigated.
Journal ArticleDOI
Effect of the perforation design on the fluid flow and heat transfer characteristics of a plate fin heat exchanger
TL;DR: In this article, the performance of vortex generators in a plate fin heat exchanger with and without perforation has been investigated, and the effect of the shape of perforations has been analyzed.
Journal ArticleDOI
A numerical study of fluid flow and heat transfer over a fin and flat tube heat exchangers with complex vortex generators
TL;DR: In this paper, the authors investigated the heat transfer and fluid flow behaviors in a fin-and-flat-tube heat exchanger provided with complex vortex generators (CVGs), and the results showed that the vortex formed near the tubes is intensified by the flat potion of CVGs, and the curved tube guide the fluid flow towards the region behind the tubes, resulting thus in improved heat transfer rates.
Journal ArticleDOI
Enhancement of the cooling of shear-thinning fluids in channel heat exchangers by using the V-baffling technique
TL;DR: In this article, the performance of a channel heat exchanger equipped with V-baffles has been evaluated using a multidimensional CFD model, and the results revealed that +V baffles inserted in the staggered arrangement may give a considerable superiority in enhanced heat transfer ratio, compared to the (−V) baffles' insertion and the aligned arrangement.
