Thermo Hydraulic Performance of a Curved Solar Air Heater with Different Shaped down Turbulators using CFD
In contrast to the flat plate SAH design, curved designs of solar air heater ducts show substantial improvement in thermal characteristics, with the former showing a slight decrease in hydraulic efficiency. The creation of secondary vortices resulting in the mixing flow is demonstrated by curved SAH due to the centrifugal effect. In addition, the creation […]
Effect of Artificially Roughness in Solar Air Heater A Review
The use of an artificial roughness on a surface is an effective technique to enhance the rate of heat transfer to fluid flow in the duct of a solar air heater. Number of geometries of roughness elements has been investigated on the heat transfer and friction characteristics of solar air heater ducts. In this paper […]
