in this paper, inflow turbulence effects on the flow wake parameters around a naca0012 airfoil at zero incidence angle and reynolds number of 38,700 were investigated. various turbulence promoter networks were used to achieve turbulence intensity of 5% and 6%. experiments have been conducted for three different turbulence intensities in which mean velocity parameters, turbulence intensity, freq...

Air-type photovoltaic thermal (PV/T) collectors have a lower heat recovery rate than liquid-type collectors. Therefore, in this study, semicircular turbulence promoters were attached to the back of PV cell improve rate. Based on computational fluid dynamics, heat-transfer performance and pressure drop evaluated by changing Reynolds number (Re) promoter shape conditions. The conditions include r...
