BOUNDARY-LAYER FLOW OF MICROPOLAR FLUID ON ROTATING AXISYMMETRICAL SURFACES WITH A CONCENTRATED HEAT-SOURCE

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