Abstract

AbstractIn this work, we study the two dimensional free‐convection boundary‐layer gas flow of a viscous and incompressible fluid near a moving porous, infinite and vertical plate (or wall) in the presence of heat sources/sinks. Exact solution of this problem is found with the help of Laplace transform technique. Analytical expressions of this solution for velocity, temperature, skin‐friction, and rate of heat transfer have been developed. The corresponding expressions for nonporous plate are discussed. The derived results are also discussed in details with the help of graphs for vertical air flows, in order to observe the effects of various governing parameters, such as the heat source/sink parameter. Furthermore, a comparison between the results obtained for porous plate and nonporous plate is illustrated in these graphs.
