CFD Analysis of a W Ribbed Roughness Solar Air Heater
Solar air heaters are used to heat up air which can be used for various purposes. Computational Fluid Dynamics CFD has proved to be a boon for researchers to estimate performance of any machine at design stage only. In the present work, a 3 dimensional CFD investigation has been completed of sun powered air radiator to ponder heat exchange and liquid stream conduct in a rectangular pipe of a sun oriented air warmer with one roughened divider having blend of round and square transverse wire rib harshness. The impact of Reynolds number, harshness tallness, unpleasantness pitch, relative unpleasantness pitch and relative harshness stature on the warmth exchange coefficient and rubbing factor have been considered. From the investigation it has been found that, W formed harshness gives better warmth exchange rate as contrast with the V rib unpleasantness under comparable working conditions. The most extreme estimation of Nusselt number for W formed harshness is acquired with the relative unpleasantness pitch P e of 10 past that it begins diminishing.
