MASS-TRANSFER EFFECTS ON FLOW PAST AN IMPULSIVELY STARTED INFINITE VERTICAL PLATE WITH CONSTANT MASS FLUX - AN EXACT SOLUTION

An exact solution to the problem of flow past an impulsively started i nfinite vertical plate in the presence of a foreign mass and constant mass flux at the plate is presented by the Laplace-transform technique . The velocity, the temperature and the concentration profiles are sho wn on graphs. The skin-friction and the Sherwood number are also shown on graphs. The effects of different parameters like G (the Grashof nu mber), Gc (the modified Grashof number), Pr (the Prandtl number) and S c (the Schmidt number) are discussed.
