Radiation effects on flow past an exponentially accelerated isothermal vertical plate with mass flux

Thermal radiation effects on unsteady flow of a viscous incompressible fluid past an exponentially accelerated infinite isothermal vertical plate with uniform mass flux has been studied. The fluid considered here is a gray, absorbing-emitting radiation but a non-scattering medium. The plate temperature is raised to Tw and the concentration level near the plate is also made to be at a constant rate. An exact solution to the dimensionless governing equations has been obtained by the Laplace transform method, when the plate is exponentially accelerated with a velocity […] in its own plane. The velocity, temperature and concentration fields are studied for different physical parameters such as the thermal Grashof number, mass Grashof number, Schmidt number, a and time. It is observed that the velocity increases with increasing values of a or t.

Flow past an exponentially accelerated vertical plate with heat and mass flux

A theoretical solution for an unsteady flow past an exponentially accelerated infinite the vertical plate with prescribed uniform heat and mass flux is analyzed. The plate temperature and the concentration level near the plate are raised at a uniform rate. The dimensionless governing equations are solved using Laplace - transform technique. Velocity, temperature and concentration fields are studied for different physical parameters such as the thermal Grashof number, mass Grashof number, Schmidt number, and time. It is observed that velocity increases with increasing values of [...].
