Abstract

In the present work we study the free convection flow past an impulsively started infinite, vertical porous limiting surface (e.g. of a star) which is subjected to a constant suction velocity, with heat ‘sources’ when the free stream velocity oscillates in time about a constant mean. A perturbation solution is sought for obtaining the expressions of mean velocity and mean temperature. The results are compared with the corresponding ones without heat sources.
