Numerical solution of combined convective heat transfer of micropolar fluid in an annulus of two vertical pipes
Abstract
The problem of free and forced convective heat transfer of micropolar fluid in an annulus of two vertical pipes has been studied by applying Runge-Kutta-Merson method. It has been found that when the temperature of the pipes decreases with height, the presence of micropolar elements delays the onset of instability. When the temperature increases with height, it has been noticed that microrotation enhances the back flow. Effects of micropolar parameters and Rayleigh number on heat transfer are discussed.
