Velocity potential for doublet Calculator

The velocity potential (φ) for a doublet in fluid dynamics is a scalar function used to describe the irrotational flow pattern created by a doublet source-sink combination. A doublet is a hypothetical flow pattern that consists of a source (a point that emits fluid) and a sink (a point that absorbs fluid) of equal strength located very close to each other. 

  • φ is the velocity potential, a scalar field used to describe irrotational flow patterns in aerodynamics.
  • 𝜅 (kappa) is the strength of the doublet, which represents the intensity or magnitude of the doublet flow.
  • 𝜃 (theta) is the polar angle, measured in radians, with respect to the center of the doublet.
  • r is the radial distance from the center of the doublet.
