The radial velocity for a source flow refers to the component of velocity that is directed radially away from or towards a central point source of fluid. A source flow is an idealized model in which fluid is continuously emanating from a point source (or converging towards a point sink).
- Vr: Radial velocity component in the source flow.
- Λ: Strength of the source, which is a constant representing the flow rate or the magnitude of the source.
- r: Radial distance from the source point.
