Analysis of Thermo Hydraulic Performance of Artificial V-Rib Roughness of Solar Air Heater: A Review
Abstract: Solar air heaters (SAHs) are the simplest energy conversion device which transforms incoming solar radiation to thermal energy. In traditional SAH the convective heat transfer rate is low. To improve heat transfer rate the artificial rib roughness is employed on the absorber plate. Although rib roughness increases the heat transfer rate, as well as the pressure drop due to friction. So in order to achieve maximum increment in thermo hydraulic …
