Effect of imposed shear on the dynamics of a contaminated two-layer film flow down a slippery incline

The linear instability of a surfactant-laden two-layer falling film over an inclined slippery wall is analyzed under the influence of external shear, which is imposed on the top surface of the flow. The free surface of the flow and the interface among the fluids are contaminated by insoluble surfact...
