摘要：

Unsteady free convection flow of an elasto-viscous fluid past an infinite plate with constant suction and heat sources analyzed. Walters 'B' fluid model is used to formulate the problem. The present study is an humble attempt to throw adequate light on the effect of the heat sources on a two-dimensional unsteady free convection flow of an incompressible elasto-viscous fluid past an infinite vertical porous plate under the following physical conditions: (i) Constant suction (ii) The plate temperature oscillating in time about a constant non-zero mean. (iii) Presence of the temperature-dependent sources in the field. Approximate solutions have been derived for the mean velocity and temperature fields, the transient velocity and temperature fields, the amplitude and the phase of the skin friction and of the rate of heat transfer. It is observed that the elasticity of the fluid increases the mean velocity. The skin-friction increases with the increase of source-strength. Consequently mean temperature also rises.
