A new system of local flat plate solar water heater “LPSH” recommended to be used for heating as step maximizing renewable source energy instead traditional power.The is heat from the atmospheric temperature. Evacuated, double and single glasses were fabricate with same dimensions installed at a latitude angle 31 degree facing towards N-S direction.The experiment has been carried out 24th March...

Abstract The mean wake of a three-dimensional surface-mounted rectangular flat plate was studied experimentally in low-speed wind tunnel for four different aspect (height-to-width) ratios, AR = 3, 2, 1, and 0.5. Reynolds number based on the width Re 3.8 × 10 4 boundary layer thickness ground plane, relative to width, δ / W 1.1. incidence angle varied from α 0° (where is normal flow) 90° paralle...

A prototype concentrating photovoltaic (CPV) module was designed and constructed with a low concentrating dielectric compound parabolic concentrator (DiACPC) for outdoor characterisation. The designed concentrator has acceptance half angles of 0 & 55 with a concentration ratio of 2.8. This concentrator design is suitable for building facade integration in higher latitude (>55 ) locations. A sma...
