Title

Flow and Heat Transfer in a Saturated Porous Medium over a Stretching Surface

Abstract

An analysis is carried out to study the flow heat and transfer characteristics in a saturated porous medium over an impermeable stretching sheet with frictional heating and internal heat generation or absorption. Two cases are studied, namely (i) the sheet with prescribed surface temperature (PST‐case) and (ii) the sheet with prescribed wall heat flux (PHF‐case). Exact solutions for the velocity field and the skin friction are obtained. Also, the solutions for the temperature, the heat transfer characteristics and their asymptotic limits for large and small Prandtl numbers are obtained in terms of Kummer's and parabolic cylinder functions. For large Prandtl numbers (σ), a thermal boundary layer width of √l/σ is noticed in both PST and PHF cases. Furthermore, it is shown that there is no boundary layer type of solution for small Prandtl number.
