MASS-TRANSFER EFFECTS ON FLOW PAST A VERTICAL OSCILLATING PLATE WITH VARIABLE-TEMPERATURE

An exact solution to the flow of a viscous incompressible Gr fluid past an infinite vertical oscillating plate, in the presence of a foreign mass has been derived by the Laplace-transform technique when the plate temperature is linearly varying as time. The velocity profiles are shown on graphs and the numerical values of the skin-friction are listed in a table. It is observed that the skin-friction increases with increasing Sc, Tt, omega t or Gr but decreases with increasing Gm or t, where Sc (the Schmidt number), omega (frequency), t (time), Gr (the Grashof number) and Gm is (the modified Grashof number) and t.
