Summary:Title screen
An analysis of natural convective flow and heat transfer of a micropolar fluid in a wavy differentially heated cavity has been performed. Governing partial differential equations formulated in non-dimensional variables have been solved by finite difference method of second order accuracy. The effects of Rayleigh number (Ra = 104, 105, 106), Prandtl number (Pr = 0.1, 0.7, 7.0), vortex viscosity parameter (K = 0, 0.1, 0.5, 2.0) and undulation number (κ = 1, 2, 3) on flow patterns, temperature fields and average Nusselt number at hot wavy wall have been studied. It is found that microrotation increases as the vortex viscosity parameter K increases. However, the fluid velocity decreases as Kincreases. It is observed that the form of streamlines is dependent on the value of vortex viscosity parameter. An increase in the undulation number leads to a decrease in the heat transfer rate at wavy wall.
