Approximating Flow Separation over a Half Cylinder

WebUniform Flow with Source Two or more incompressible, irrotational flows can be combined by superposition, simply by adding their velocity fields or their potential or stream function fields. Superposition of a uniform flow in the x-direction and a source at the origin therefore has u(x,y) = Λ 2π x x2 +y2 + V ∞ v(x,y) = Λ 2π y x2 +y2 ... WebFlow around a circular cylinder can be approached from the previous example by bringing the source and the sink closer. Then we are considering a uniform flow in combination with a doublet.
