In a two-dimensional potential flow, the doublet is a limit of the superposition of

In a potential flow, a uniform stream of strength U directed along the x-axis and four line sources (2-dimensional) of strengths π/2, π/4, π/5, and -π/5 are pla...

Consider a two-dimensional potential flow over a cylinder. If the freestream speed is U∞, the maximum speed on the cylinder surface is
