MHD effects on exponentially accelerated vertical plate with variable temperature and mass diffusion

Sathappan K. E., Muthucumaraswamy R.

International Journal of Applied Mechanics and Engineering

2012

Vol. 17, no. 1

289-297

An exact solution of an unsteady flow past an exponentially accelerated infinite vertical plate with variable temperature and mass diffusion is presented in the presence of a magnetic field. The plate temperature and species concentration level near the plate is made to rise linearly with time. The dimensionless governing equations are solved using the Laplace-transform technique. Velocity, temperature and concentration profiles are studied for different physical parameters such as the magnetic field parameter, thermal Grashof number, mass Grashof number, Schmidt number, time and parameter a. It is observed that velocity decreases with increasing the magnetic field parameter. It is also observed that the velocity increases with increasing values of a.

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

Muthucumaraswamy R., Sathappan K. E., Natarajan R.

International Journal of Applied Mechanics and Engineering

2009

Vol. 14, no 4

1029-1038

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

Muthucumaraswamy R., Sathappan K. E., Natarajan R.

International Journal of Applied Mechanics and Engineering

2008

Vol. 13, no 4

979-986

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 [...].
