Boundary layer flow of micropolar fluid on rotating axisymmetric surfaces with a concentrated heat source

Abstract

The theory of micropolar fluids due to Eringen is used to formulate a set of boundary layer equations for the convective flow of an incompressible micropolar fluid on rotating adiabatic axisymmetric surfaces with a concentrated heat source located at the tip. The velocity and thermal boundary layers spread because of the centrifugal forces induced due to rotation. Similarity transformations are presented for the conservation equations and these are solved numerically. The effects of the boundary conditions used for the microrotation term are discussed.
