FREE Convective Heat Transfer from Inclined Narrow Plates

Abstract

Natural convection has attracted a great deal of attention from researchers because of its presence both in nature and engineering applications. In nature, convection cells formed from air raising above sunlight-warmed land or water are a major feature of all weather systems. Con-vection is also seen in the rising plume of hot air from fire, oceanic currents, and sea-wind formation (where up-ward convection is also modified by Coriolis forces). The main object of the paper is to provide an analysis based on the effect of inclination angle from vertical on the heat transfer from flat plates is determined. Natural convec-tive heat transfer from flat plates inclined at an angle to the vertical in laminar flow regions has been analytically investigated. The inclination angles are 150, 300, 450 and 600. The models are done in Pro/Engineer. The fluid flow characteristics considering laminar flow under natu-ral convection is analyzed using CFD analysis. The heat transfer rates by using different materials for plates are analyzed using thermal analysis. The materials taken are Copper and aluminum alloy 6061.In many applications, convection is commonly visualized in the formation of microstructures during the cooling of molten metals, and fluid flows around shrouded heat-dissipation fins, and so-lar ponds. A very common industrial application of natu-ral convection is free air cooling without the aid of fans: this can happen on small scales (computer chips) to large scale process equipment.
