ABSTRACT

A boundary layer analysis is presented to study the mixed convection flow of a micropolar fluid over a vertical non-isothermal flat plate. The transformed boundary layer equations have been solved numerically. The effects of buoyancy and micropolar parameters and Prandtl number on the velocity, angular velocity, and temperature distribution are discussed. The missing wall values of the velocity, angular velocity, and thermal functions are computed. Micropolar fluids display drag reduction and reduce surface heat transfer rate when comparing with Newtonian fluids.
