Effect of Heat and Mass Transfer on Natural Convective Flow of Micropolar Fluid in Vertical Concentric Cylinders
Author(s): Arun Kumar Singh, A. K. Singh
Keywords: Micropolar fluid, Natural convection, Temperature, Concentric vertical cylinder
Free convection of a micropolar fluid is examined analytically in order to see the effect of heat and mass transfer in concentric vertical cylinders. The model of governing equations in non-dimensional velocity, microrotational velocity and temperature using the Boussinesq and Eringen equation with suitable boundary conditions are expressed in terms of cylindrical coordinate system and then exact solution one obtained. The influence of the non-dimensional physical parameters such as the vortex viscosity ratio, material and temperature ratio parameters on the velocity, microrotational velocity and the skin friction at the surface of cylinder has been studied by using graphs and table.
