- Abstract
Theoretical solution of unsteady radiative flow past a uniformly accelerated isothermal infinite vertical plate with
uniform mass diffusion is presented here, taking in to account the homogeneous chemical reaction of first order. The
plate temperature is raised to w T and the concentration level near the plate is also raised to /
w C . The dimensionless
governing equations are solved using Laplace-transform technique. The velocity, temperature and concentration
fields are studied for different physical parameters like thermal Grashof number, mass Grashof number, Schmidt
number, Prandtl number, radiation parameter, chemical reaction parameter and time. It is observed that the velocity
increases with increasing values of thermal Grashof number or mass Grashof number. But the trend is just reversed
with respect to the thermal radiation parameter. It is also observed that the velocity increases with decreasing
chemical reaction parameter.
