Spatial stability analysis is used in the present paper in order to investigate the effect of variable friction on spatial growth rates of an unsteady perturbation. The flow is assumed to be slightly curved in the longitudinal direction. Numerical scheme is developed for the solution of the spatial stability problem. Numerical results show that growth rate of a perturbation decreases in the presence of regions of non-uniform friction. In addition, small curvature stabilizes the flow.
