A numerical simulation is performed to study the effect of two types vortex generators (VGs) on heat transfer coefficient and pressure drop in duct. There are V.G., one concave V.G. other rectangular. The aim observe effects shape arrangement this V.Gs channel increase with Reynolds number range from (300 1500). Both were placed 45o angle attack, an line staggered position. results shows that p...

The effect of streamwise plasma vortex generators on the convective heat transfer a turbulent boundary layer is experimentally investigated. A Dielectric Barrier Discharge (DBD) plasma-actuator array employed to promote pairs counter-rotating, streamwise-aligned vortices embedded in well-behaved over flat plate. study aims at elucidating mechanism interaction between plasma-induced vortical str...

Vortex generators are used to overturn the momentum of flow in boundary layer, thereby preventing separation, and broadly aviation, wind power, heat exchange, different fields. It has been determined that capability an eddy current generator manipulate layer is proportional intensity vortex strength it excites. Although mathematical notion very well defined, there difficulties figuring out appl...

in this paper the effect of block shape vortex generators (vgs) on an air-water fin-tube heat exchanger has been studied experimentally using exergy analysis method. also the effect of these vgs on increasing heat transfer rate has been simulated numerically and the results show a good agreement with the experiments. in this research we used a wind tunnel to produce wind flow over heat exchange...
