LAMINAR MIXED CONVECTION HEAT-TRANSFER IN 3-DIMENSIONAL HORIZONTAL CHANNEL WITH A HEATED BOTTOM

Mixed convection heat transfer phenomena are studied in a three-dimens ional channel with a cavity heated from below. A general purpose compu ter program is developed to analyze the flow field and temperature dis tribution in the channel. Numerical computation is performed by using the alternating direction implicit (ADI) method based on the SIMPLER a lgorithm. The influences of Reynolds number and Grashof number on the Nusselt number of the cavity are discussed. As a convenience to the re ader, three-dimensional streaklines and three-dimensional isothermal s urfaces are presented.
