| dc.description.abstract | This paper presents a review on the heat transfer increase and reduction in pressure drop for compact heat exchangers (CHXs) by using protrusion of surfaces in the form of surfaces in the form of vortex generators (VGs). The effect of the shape, angle of attack and various other types of VGs are discussed. The purpose of this study is to collect various information on the features of CHXs that are presented by experimental and numerical studies for improving the design of heat exchangers. The effects of different shapes of VGs, their configuration, location and angles of attack on the heat transfer augmentation and drop of pressure decrease of heat exchangers have been examined. Longitudinal vortex generators that are induced by VGs have proved to cause a reduction in the weaker heat transfer region behind tubes and promote better mixing and turbulence intensity. Nevertheless, the strength and intensity of vortices still depend on Reynolds number. | en_US |
