NATURAL CONVECTIVE HEAT TRANSFER FROM A NARROW VERTICAL FLAT PLATE WITH A UNIFORM SURFACE HEAT FLUX AND WITH DIFFERENT PLATE EDGE CONDITIONS

摘要

Natural convective heat transfer from narrow vertical plates which have a uniform surface heat flux has studied. With a narrow plate the heat transfer rate is dependent on the flow near the vertical edges of the plate. The magnitude of the edge effects will depend on the conditions existing near the edges of the plate. Three situations have here been considered these being a heated plate imbedded in a large plane adiabatic surface, the surfaces of the heated plane and the adiabatic surface being in the same plane, a heated plate with plane adiabatic surfaces above and below the heated plate, and a heated plate that is attached to a large parallel plane adiabatic surface but protrudes from the adiabatic plane surface. The effect of the edge condition on the heat transfer rate has here been numerically investigated.
