The flow of micropolar fluids through a microparallel channel with corrugated walls is performed in this paper. The corrugations of the two walls are described as periodic sinusoidal waves with small amplitude and phase difference theta. The flow generated by the constant pressure gradient is assumed to be steady and unidirectional. Approximate analytical solutions of velocity, vorticity of micro-rotation and volume flow rate are obtained by perturbation techniques. The effects of the corrugation on the flow are graphically analyzed by using numerical computation. The dependences of velocity, vorticity of micro-rotation and leading-order perturbations to the mean velocity of micropolar fluids on the Reynolds number Re, the phase difference theta of the two corrugated walls and couple stress parameter s(0) are explained graphically.
