Consider steady, incompressible, two-dimensional flow through a converging duct. A simple approximate velocity field for this flow is V = (u, v) = (U, + bx)i – byj O. Note that this equation ignores viscous where UO is the horizontal speed at x = effects along the walls but is a reasonable approximation throughout the majority of the flow field. Find an analytical equation of streamline for this flow.
