The effect of the volume flow rate of the heat transfer fluid (air) on the thermal parameters of the solar air collector with a single air pass without using fins under the absorbing plate have been investigated experimentally and theoretically. We use a new design of solar air collector which aims to optimize these parameters in the region cited above. Our solar air collector was realized at t...

A new design of Solar Air Heater (SAH) with triangle cross-section is numerically studied. The thermal performance SAH studied at various mass flow rates, inlet air temperatures and solar irradiation intensities. CFD model developed using the software ?ANSYS Fluent? to study fluid heat transfer in heater. 3D discretization applied collector cross section. Mesh independence performed order choos...

In this paper, performance analysis of a hybrid photovoltaic-thermal (PV/T) greenhouse air heater and dryer has been carried out. Analytical expressions have been developed for • greenhouse air temperature, instantaneous and overall energy and exergy efficiencies for without load and • instantaneous exergy efficiency with load under forced mode operation. An experimental validation has been car...
