Augmented heat transfer in a turbulent channel flow with inclined detached-ribs

Novel design of delta winglet pair vortex generator for heat transfer enhancement

“…dard k-u model. Moreover, the SST k-u model was used by several researchers in previous works and it shows a fair agreement with experimental results for flow configurations similar to the present study [39,40].…”

Effect of roughness width ratios in discrete multi V-rib with staggered rib roughness on overall thermal performance of solar air channel

“…The CFD simulation involves mathematical solutions of the conservation equations for mass, momentum and energy. These equations for incompressible streams can be written as follows Li et al (2009), Xie et al (2013 and Yongsiri et al (2014):…”

Aerodynamics and Heat Transfer over Solid-Deflectors in Transverse, Staggered, Corrugated-Upstream and Corrugated-Downstream Patterns

“…The maximum thermal enhancement factor of the 45° baffle in the Reynolds number range studied was found to be about 2.6 or twice higher than that of the 90° transverse baffle. Yongsiri et al [3] reported the results of numerical study of turbulent flow and heat transfer in a channel with inclined detached-ribs. In that study, the fluid flow, temperature field and thermal performance of the inclined detached-ribs with different attack angles (from 0° to 165°), were examined and compared with those of the typical transverse attached rib with the attack value of 90°.…”
