Abstract
Radiation effect on unsteady free convection flow of an electrically conducting, gray gas near equilibrium in the optically thin limit along an infinite vertical porous plate are investigated in the presence of strong transverse magnetic field imposed perpendicularly to the plate, taking Hall currents into account. A similarly parameter length scale (h), as a function of time and the suction velocity are considered to be inversely proportional to this parameter. Similarity equations are then derived and solved numerically using the shooting method. The numerical values of skin friction and the rate of heat transfer are represented in a table. The effects of radiation parameter, Hall parameter, and magnetic field parameters are discussed and shown graphically.
Highlights
Free convection flows past different types of vertical bodies are studied because of their wide applications and it has attracted the attention of numerous investigators and scientists
The unsteady hydromagnetic free convective flow with Hall current is studied by Singh and Raptis [9]
We investigate the solution which the buoyancy, radiation, and Hall currents act simultaneously
Summary
Free convection flows past different types of vertical bodies are studied because of their wide applications and it has attracted the attention of numerous investigators and scientists. In all these studies the Hall current effects are not considered. The unsteady hydromagnetic free convective flow with Hall current is studied by Singh and Raptis [9].
