Mixed convection flow of a micropolar fluid on a moving heated horizontal plate

Steady laminar boundary layer flow and heat transfer of a micropolar fluid over a heated isothermal horizontal plate moving in a flowing stream. has b een studied in this paper, The cases corresponding to the isothermal horizo ntal plate moving in thc same (parallel) or in. the opposite (reverse) dire ction to thp free stream are considered. Similarity and nonsimilarity equat ions of six special systems arc reduced readily front universal formulation . The governing momentum. angular momentum, and energy equations have been solved numerically. The effects (if buoyancy and relative velocity or) the flow and temperature fields including surface friction and heat transfer ra te are presented for a plate moving in parallel or reversely to the free st ream. It is observed that micropolar fluids display drag reduction when com pared to Newtonian fluids.
