Abstract.Gebhast has observed that in natural convection flow fields of extreme size or extremely low temperatures or in high gravity field, the heat due to viscous dissipation plays a dominant role. Hence taking the dissipative heat into account, the heat transfer in the hydromagnetic boundary layer flow of viscous incompressible and finitely conducting fluid along an infinite porous plate with slightly transverse sinusoidal suction has been analyzed. Expressions for velocity profile and temperature distribution are obtained. The rate of heat transfer coefficient on the surface of the plate is obtained and numerically computed to get physical insight of the problem.
