Flow with an interfacial traction. Consider the problem of a semi-infinite fluid subject to a constant shear at the interface. This can be caused, for instance, by a surface-tension gradient. Show that the following differential equation is applicable for the boundary layer: 3f + 2ff − (f ) 2 = 0 State the boundary conditions. Use the program BVP4C to simulate the flow.
