Theoretical solution of unsteady viscous incompressible flow past an
infinite vertical oscillating plate with uniform heat flux and mass
diffusion is presented here, taking into account of the homogeneous
chemical reaction of first-order. The temperature from the plate to the
fluid at an uniform rate and the mass is diffused uniformly. The
dimensionless governing equations has been obtained by the Laplace
transform method, when the plate is oscillating harmonically in its own
plane. The effects of velocity and concentration are studied for different
parameters like phase angle, chemical reaction parameter, thermal Grashof
number, mass Grashof number, Schmidt number and time are studied. The
solutions are valid only for small values of time t. It is observed that
the velocity increases with decreasing phase angle
wt or chemical reaction parameter. |
