CALCULATION OF THE EQUILIBRIUM LOCATIONS OF A VORTEX PAIR BEHIND A CIRCULAR CYLINDER WITH A SOURCE OR SINK PLACED AT THE REAR STAGNATION POINT

摘要

The equilibrium positions of a vortex pair of specified strength behind a circular cylinder in steady, potential flow have been calculated with a source or sink placed at the fear stagnation point.nThe theory indicates that a source causes the vortices to be positioned on curves which are closer to the axis of symmetry than for Cμ = 0 and are, in general, farther downstream.
