This study explores the thermal performance of double-pass photovoltaic thermal (PVT) systems by investigating the influence of turn shape on heat transfer characteristics using computational fluid dynamics (CFD) simulations. The aim is to evaluate various turn shapes, including half-circle, triangle, half-hexagon, half-octagon, and box, to determi...

Performance of solar photovoltaic (PV) system degrades considerably when the surface of the PV array is covered with shadows indicated by the reduction in the generated power. Partial shading condition causes the PV array to produce multiple peaks in PV’s characteristic curve causing the non-optimal power generation of the conventional maximum powe...

This study proposed the design of pico-scale Turgo turbine blades using triangle velocity and printing blades using three-dimensional (3D) printer technology. Then, describe the testing method of Pico scale Turgo turbines in laboratory conditions. The velocity triangle analysis accommodates backflow where it is affected by blade angle; this is rele...
