WebMay 13, 2024 · The lift equation for a rotating cylinder bears their names. The equation states that the lift L per unit length along the cylinder is directly proportional to the velocity V of the flow, the density r of the flow, and the … WebHere we use the definition of the streamfunction in cylindrical coordinates: vθ = − ∂ψ ∂r ωz = 0 = ∂(rvθ) ∂r So if we consider the flow to be given by its velocity vθ = c / r, where C is a constant, then the vorticity will be zero as required. Inserting this into the definition for the streamfunction above yields: ψ = − Cln r ψ = −Cln r (5.10) how to shrink foam
