The radial distance of a doublet refers to the perpendicular distance from the doublet source (or sink) to a specific point in the flow field. The doublet is a theoretical construct used to model certain flow patterns, and its radial distance is an important parameter when analyzing its influence on the surrounding fluid.
- r1 is the radial distance for doublet one
- Cartesian coordinate for x axis for doublet one (x1)
- Cartesian coordinate for y axis for doublet one (y1)
