Cylinder potential flow
WebThis study is aimed at understanding the effects of two-phase flow over bluff bodies. Of particular interest are cylindrical surfaces, while also looking at their wakes formed and studying the resulting drag on the body. The two-phase flow condition is used to simulate a boiling system with the cylinder being the heated surface where vapour bubbles would … WebAway from the half-cylinder the flow is irrotational, ∇ → × u → = 0 →, allowing a potential function to be defined: u = ∂ ϕ ∂ x, w = ∂ ϕ ∂ z. The incompressibility condition reduces to: ∇ 2 ϕ = 0. This is Laplace’s equation. Noting the axial symmetry, the math may be simplified by converting to polar coordinates.
