Flow of a thermomicropolar fluid with stretch

Abstract

The linear theory of micropolar fluids with stretch including the heat conduction and heat dissipation effects and restrictions imposed by the second law of thermodynamics are stated. The final equations of motion are discretized and solved for the case of a flow between two parallel and heated horizontal plates, stationary with respect to the flow. The effect of microstructure on heat transfer and fluid flow is studied thoroughly, including the contribution of terms involving inertial spin. The microrotation boundary conditions are discussed along with their influence on the velocity, gyration, and microstretch fields as well as on heat transfer. An interesting and experimentally observed phenomenon involving the appearance of two maximums in the velocity profile is noted.
