Stagnation points refer to specific locations in the flow field where the velocity of the fluid becomes zero, resulting in stagnation or zero velocity. For the flow over a cylinder, there are two primary types of stagnation points: the forward stagnation point and the rear stagnation point.
- R is the radial coordinate of the stagnation points (distance from the center of the cylinder to the stagnation points) (in m).
- μ strength of doublet (in m^2/s).
- V∞ is the freestream velocity of the fluid (in m/s).
