Tangential velocity () for a sphere refers to the component of velocity tangent to the surface of the sphere at a specific point. In other words, it is the velocity of a fluid or an object as it moves around the surface of the sphere, parallel to the surface.
- Tangential velocity (Vθ) in rad/s
- Angle (θ) in rad
- Strength of doublet (𝜇) in m^3/s
- Distance (r) in m
- Freestream velocity (V∞) in m/s
