Important new features are found for a family of swirling jets with velocity v;z, wherez is the distance from the jet origin. First, there is a sharp minimum of the pressure coefficient at a certain value of the swirl numberSw which is nearlyn independent; this feature can be utilized in technological devices. Second, as Sw increases, a separation zone develops, where the fluid is not at rest in the inviscid limit~contrary to the claims of recent vortex breakdown theories !. These results are… CONTINUE READING
