In this paper, the peristaltic transport of a micropolar fluid in an asymmetric channel with permeable walls and heat transfer is investigated. The flow is investigated in a wave frame of reference moving with the velocity of the wave. The expressions for velocity, temperature, stream function, pressure gradient and pressure rise have been obtained. The impact of various physical parameters on the velocity, the temperature, the pressure rise and the trapping phenomenon are discussed through graphs. It is found that the velocity increases with decreasing coupling number N and increasing microrotation parameter m. Also it is noticed that the temperature increases with increasing heat source/sink parameter β0 and permeability parameter γ. Further the pressure rise increases with increasing heat source/sink parameter β0 and permeability parameter γ and decreases with increasing phase difference Φ. � Research India Publications.
