In aerodynamics, uniform flow refers to a type of ideal flow pattern where the fluid velocity remains constant across a large region. In the case of two-dimensional flow (flow that occurs within a plane). The stream function () is a mathematical function used to describe the flow of an incompressible fluid (such as air) in 2D flow scenarios. It is a fundamental concept in potential flow theory and simplifies the analysis of fluid flow patterns.
- is the stream function
- is the radial distance from the origin
- is the angle
