Transient Free Convective Flow of A Micropolar Fluid Between Two Vertical Walls

The aim of this paper is to present numerically the transport mechanism of an incompressible microp-olar uid between two vertical walls when the motion occurs due to the buoyancy force. the governingequations in non-dimensional form are solved numerically using the matlab software. the obtainednumerical solutions for the velocity and micro-rotation proles are displayed using the graphs forvarious values of the vortex viscosity parameter and material parameter. it is found that the materialparameter has retarding eect on the velocity of micropolar uid and to make the ow steady stateearlier for both thermal conditions. the eect of the vortex viscosity parameter is to decrease thesteady state time of the velocity and micro-rotation.
