Abstract Steady laminar boundary layer flow and heat transfer of a micropolar fluid over a heated isothermal horizontal plate moving in a flowing stream has been studied in this paper. The cases corresponding to the isothermal horizontal plate moving in the same (parallel) or in the opposite (reverse) direction to the free stream are considered. Similarity and nonsimilarity equations of six special systems are reduced readily from universal formulation. The governing momentum, angular momentum, and energy equations have been solved numerically. The effects of buoyancy and relative velocity on the flow and temperature fields including surface friction and heat transfer rate are presented for a plate moving in parallel or reversely to the free stream. It is observed that micropolar fluids display drag reduction when compared to Newtonian fluids.
