  • Abstract:
  • In the present paper, Hall Effects with Radiation effects on unsteady free convection flow and mass transfer over an infinite vertical porous plate which is embedded in porous medium with heat source. The basic governing equations of the problem are transformed into a system of non dimensional differential equations, which are then solved analytically by using Perturbation techniques. The dimensionless Velocity, temperature and concentration profiles are displayed graphically showing the effects fluid flow for the different values of the parameters involving in this problem like permeability parameter Kp,Grashof numbers Gr, Gc for heat and mass transfer, Heat Source parameter (S),Schmidt Number(Sc),Prandtl Number (Pr),Radiation Parameter(R) Second Order Chemical reaction parameter (〖Kr〗^2) etc.,. It is interesting to note that an increase of Grashof number(Gr),Permeability parameter(Kp) Grashof Number (Gc) accelerates the transient velocity of fluid.But increase of Heat Source parameter (S)retards the velocity profile of fluid flow.Further, it is observed that the temperature profile of the fluid flow decrease while increasing of prandtl number(Pr) and Radiation Parameter(R).But increase of Grashof number(Gr),shows the reverse process.The effect of increasing Schmidt number(Sc) and Chemical reaction parameter (〖Kr〗^2) is to decrease the concentration boundary layer thickness of the flow field.Further, a growing of Magnetic Parameter (M) and Hall Parameter (m) increasing the skin friction at the wall expect (Pr=5) and growing of Magnetic Parameter (M) and Hall Parameter (m) leads to increase the magnitude of the rate of heat transfer at the wall expect (Pr=0.71).While Chemical reaction parameter (〖Kr〗^2) increase, shows the decrease effects of the rate of mass transfer at the wall.The investigated results showed graphically that the flow field is notably influenced by the considering parameters.
