Inviscid ( μ = 0) 2. Incompressible 3. Irrotational It describes the flow around streamlined objects far away from the object. (In the near field the boundary layer theory is used) This type of problems deals with more than one velocity component, and function in more than one independent variable.
Potential Flow To solve them in an easy way conformal mapping is used. So instead of solving N-S equations to get the velocity profile, complex potential is used. w(z) = ϕ (x, y) + i ψ (x, y) Where: 1. ϕ (x, y) is the velocity potential 2. ψ (x, y) is the stream line function 3. z = x + i y = r e i θ = r cos θ + i sin θ The three forms of z are equivalent to each other, choose the one that makes your solution easier !!
Potential Flow For a given function to represent a potential flow: 1. Cauchy-Riemann conditions should be verified 2. Ψ = constant, represent the solid surface.
