Thank you. But could you explain it in detail? I don't quit understand. Should the stream function satisfy the lapace equation both inside and outside the boundary? I think when we assume the flow is inviscid, we don't consider the boundry layer thus there is no "friction" between the fluid and...
Thank you for the reply.
I think I didn't make the problem clear. The fluid is assumed to be irrotional, inviscid, and incompressible. So when there is a body moving in the fluid, there is no friction on the surface. In other words, when the circular cylinder (x^2+y^2 =R^2) has a constant...
Hi...
Suppose we consider a circular cylinder moving with constant velocity U in x-direction in a two-dimensional unbounded, irrotional, incompressible, inviscid fluid. If the motion of the fluid is completely resulted from the motion of the body, we know the velocity field of fluid can be...
