Numerical study on flow past an oscillating plate with variable temperature and uniform mass diffusion under chemical reaction

Vijayalakshmi A. R., Selvajayanthi M.

International Journal of Applied Mechanics and Engineering

2014

Vol. 19, no. 1

181--193

An numerical study on an unsteady flow past an oscillating semi-infinite vertical plate with variable temperature and uniform mass diffusion under the influence of a first order chemical reaction has been carried out. The dimensionless governing equations are solved by an unconditionally stable and fast converging implicit finite difference scheme. The effects of velocity and temperature for different physical parameters such as the chemical reaction parameter, thermal Grashof number, mass Grashof number and time are analysed. It is observed that due to the presence of first order chemical reaction, the velocity increases during a generative reaction and decreases in a destructive reaction.

Radiation effects on oscillating vertical plate with uniform heat and mass flux

Vol. 18, no. 3

643--652

Thermal radiation effects on flow past an impulsively started infinite vertical oscillating plate with uniform heat and mass flux is studied. The fluid considered here is a gray, absorbing-emitting radiation but a nonscattering medium. The dimensionless governing equations are solved using the Laplace-transform technique. The velocity, temperature and concentration are studied for different physical parameters such as the radiation parameter, phase angle, Schmidt number and time. The variation of the skin-friction for different values of the parameters is also shown in a table.

Radiation effects on MHD flow past a vertical oscillating plate with variable temperature

International Journal of Applied Mechanics and Engineering

1009-1016

Thermal radiation effects on an MHD flow past an infinite vertical oscillating plate in the presence of variable temperature is considered. The temperature near the plate is made to rise linearly with time. The fluid considered is a gray, absorbing-emitting radiation but a non-scattering medium. The dimensionless governing equations are solved using the Laplace-transform technique. The velocity and temperature are studied for different parameters like magnetic field parameter, radiation parameter, phase angle and time. The variation of the skin-friction for different values of the parameters is also shown in a table.

Thermal radiation effects on MHD flow past a vertical oscillating plate

The free convection MHD flow of a viscous incompressible fluid past an infinite vertical oscillating plate in the presence of thermal radiation is studied here. The fluid considered is a gray, absorbing-emitting radiation but a non-scattering medium. An exact solution to the governing equations is obtained by the Laplace-transform technique. The effects of the magnetic field parameter, radiation parameter, Grashof number, Prandtl number, phase angle and time on velocity and temperature fields are shown graphically and discussed. The variation of the skin-friction for different values of the parameters is also shown in a table.
