An experimental investigation of heat transfer enhancement in a rectangular duct with plate fins
(2009)
In this study, using an ideal heat exchanger model, a detailed evaluation of performance parameters in the turbulent regime for the enhancement of heat transfer by using winglet-type vortex generators is carried out. The ...
Experimental investigation of impinging jet array heat transfer from a surface with V-shaped and convergent-divergent ribs
(2012)
Detailed heat transfer measurements over a surface with V-shaped ribs (V-SR) and convergent-divergent shaped ribs (CD-SR) by a circular impinging jet array was investigated using thermal infrared camera. Both V-SR and CD-SR ...
Numerical investigation of heat transfer using impinging jets on triangular and square ribbed roughened walls
(Turkish Society for Thermal Science and Technology, 2017)
This paper presents a heat removal study on triangular and square ribbed surfaces under an array of impinging air jets. The investigation was carried out using nozzles with a 7x3 rectangular array of circular jets. The ...

Second law analysis and heat transfer in a cross-flow heat exchanger with a new winglet-type vortex generator
(Elsevier Ltd, 2010)
In this paper a second law analysis of a cross-flow heat exchanger (HX) is studied in the presence of a balance between the entropy generation due to heat transfer and fluid friction. The entropy generation in a cross-flow ...
Experimental study on the heat transfer and pressure drop of a cross-flow heat exchanger with different pin-fin arrays
(2011)
In this study, convective heat transfer and pressure drop in a cross-flow heat exchanger with hexagonal, square and circular (HSC) pin-fin arrays were studied experimentally. The pin-fins were arranged in an in-line manner. ...
