...Nirmal Halder The effects of vortex generator distance from film cooling holes on increasing gas turbine blade film cooling efficiency have been studied experimentally. The technique of infrared (IR) thermography has been implemented to study the temperature field. The diameter of the film cooling...

...B. Mehra; J. V. Simo Tala; C. Habchi; S. Russeil; D. Bougeard For a rectangular channel flow, a variant of delta winglet vortex generator (VG) in common flow up (CFU) orientation is presented to enhance the thermal performance factor by decreasing the friction losses. The new vortex generator...

...-wall vortex on the endwall surface. A vortex generator (VG) was installed in front of a discrete fan-shaped hole to produce a vortical environment on a flat plate. Heat transfer effects were experimentally studied for mainstream velocities of 20 m/s by measuring the adiabatic film cooling effectiveness...

...Uddip Kashyap; Koushik Das; Biplab Kumar Debnath In order to cool a heated surface surrounded by fluid flow, vortex generator plays a significant role. The presence of a vortex generator in the flow creates both latitudinal and longitudinal vortices. The vortices energize the boundary layer over...

... fluid dynamics (CFD) is used to conduct numerical studies on the battery packs. The results concluded that by adding both the delta winglet (DW) vortex generator arrays and jet inlet arrays in the same configuration, improvements in temperature reduction and uniformity can be achieved. The results...
