Abstract

The effects of radiation on transient natural convection of a viscous incompressible fluid confined between vertical walls have been studied. We have considered the two different cases (i) flow due to the impulsive motion and (ii) flow due to accelerated motion of one of the walls. The governing equations are solved analytically using the Laplace transform technique. The variations of velocity and fluid temperature are presented graphically. It is observed that the velocity increases for both the impulsive motion as well as the accelerated motion of one of the walls with an increase in radiation parameter. It is also observed that the velocity decreases with an increase in either Prandtl number or time for both the impulsive motion as well as the accelerated motion. An increase in Grashof number leads to a fall in velocity due to enhancement in buoyancy force. An increase in the radiation parameter leads to increase the temperature of the flow field. Further, the shear stress at the moving wall increases for both the impulsive motion as well as the accelerated motion of one of the walls with an increase in radiation parameter. The rate of heat transfer increases with an increase in either radiation parameter or Prandtl number while it decreases with an increase in time.
