Flow Around a Circular Cylinder University of Cambridge

Flow 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. The stream function and the velocity potential for this flow are given by,

Complex Velocity Potential

•Learn about the potential function, known as the velocity potential. Learn that the velocity components can be determined from the velocity potential. •Learn that the equations of motion for irrotational flow reduce to a single partial differential equation for velocity potential known as the Laplace equation. •Examine the classical analytical techniques described for obtaining two

Complex Velocity Potential

Stream function theory is particularly important in nonlinear wave representation, so it is worth going into a little detail here. For consistency with the original literature referenced below, we use slightly different conventions on this page only to the rest of the OrcaFlex documentation.

Velocity potential and stream function in GATE FLUID

The first one tackles the problem in terms of the velocity potential with normal derivative prescribed at the boundary. An integral equation method based on a distribution of vortices is utilised to solve the flow. As for the second approach the governing equation is written in terms of the stream function. Treftz method is then used to express the solution as a power series of the fundamental

The Finite Element Discretization for Stream-Function

General Solution of the Incompressible, Potential Flow Equations CHAPTER 3 Developing the basic methodology for obtaining the elementary solutions to potential flow problem. Linear nature of the potential flow problem, the differential equation does not have to be solved individually for flow fields having different geometry at their boundaries. Instead, the elementary solutions will be
