Thermal radiation effects on unsteady free convective flow of a viscous
incompressible flow past an infinite vertical oscillating plate with
variable temperature and mass diffusion has been studied. The fluid
considered here is a gray, absorbing-emitting radiation but a
non-scattering medium. The plate temperature is raised linearly with
respect to time and the concentration level near the plate is also
raised linearly with respect to time. An exact solution to 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, temperature and concentration are
studied for different parameters like phase angle, radiation parameter,
Schmidt number, thermal Grashof number, mass Grashof number and time are
studied. It is observed that the velocity increases with decreasing
phase angle wt. |
