Now, for a sheet δ n → 0 and if ζ is so large that the product ζδn remains finite, the sheet is termed a vortex sheet of strength k = ζ δ n . WebVelocity potential function and stream function are two scalar functions that help study whether the given fluid flow is rotational or irrotational. Both the functions provide a specific Laplace equation. The fluid flow can be rotational or irrotational flow based on whether it satisfies the Laplace equation or not. high cost allowance
