Thermal radiation effects on an unsteady free convection and mass transfer over a moving vertical plate in a rotating fluid are considered theoretically. An exact solution is obtained for the axial and transverse components of the velocity by defining complex velocity. The effects of velocity, temperature and concentration for different parameters such as radiation parameter, rotation parameter, Schmidt number, thermal Grashof number, mass Grashof number, Prandtl number and time on the plate are discussed.

The unsteady hydro-magnetic free convection heat and mass transfer flow of an incompressible, viscous Boussinesq fluid over a moving isothermal vertical porous plate with variable mass diffusion in the presence of thermal radiation and first order chemical reaction between the fluid and the diffusing species under the influence of a uniform magnetic field applied normal to the flow are investigated. The fluid is considered a gray, absorbing-emitting radiation but a non-scattering porous medium. The dimensionless governing equations for this investigation are solved numerically by using the Ritz finite element method. The results obtained are discussed with the help of the graphs and tables to observe the effects of various parameters such as [...]. The numerical values of the skin-friction coefficient are presented in a table. Results obtained show that a decrease in the velocity and temperature when the Prandtl number and the radiation parameter are increased and the flow velocity approaches steady state as the time parameter , is increased. These findings are in quantitative agreement with studies reported earlier.

An exact analysis is performed to study the unsteady flow past an infinite vertical oscillating plate with variable temperature and mass diffusion, in the presence of thermal radiation and homogeneous chemical reaction of first order. The fluid considered here is a gray, absorbing-emitting radiation but a non-scattering medium. 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 physical parameters like phase angle, radiation parameter, chemical reaction parameter, Schmidt number, thermal Grashof number, mass Grashof number and time. It is observed that velocity increases with decreasing the phase angle. It is also observed that velocity increases with decreasing the thermal radiation parameter or chemical reaction parameter.

Thermal radiation effects on unsteady free convective flow of a viscous incompressible flow past an infinite isothermal vertical oscillating plate with uniform 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 to [...] and the concentration level near the plate is also raised to [...]. An exact solution to the dimensionless goveming equations has been obtained by the Laplace transform method, when the plate is oscillating harmonically in its own pIane. The effects of velocity, temperature and concentration are studied for different parameters such as the phase angle, radiation parameter, Schmidt number, thermal Grashof number, mass Grashof number and time. It is observed that the velocity increases with decreasing phase angle [...].
