Energy and material saving considerations, as well as economic incentives, have led toward making effort for producing more efficient heat exchange equipment such as solar air heaters, heat exchangers. In order to enhance the heat transfer rate to flowing air in the duct of solar air heater and...

The use of turbulators in different forms of ribs, baffles, delta winglets, obstacles, vortex generator, rings and perforated blocks/baffles is an effective way to improve the performance of heat exchangers and solar air heaters. Investigators studied the effect of these turbulators for heat...
