Abstract
We consider the unsteady behavior of the e owe eld due to the slicing of a jet and a vortex with axial e ow, that is, a vortex jet, by a pair of thin e at plates. In the case of a vortex, the geometry is an idealization of the collision between a tip vortex shed from a rotor blade and two downstream stator blades in an axial e ow turbomachine. The e ow is assumed to be inviscid, and the main result of the calculations is that the vorticity e eld near each plate is radically altered. The role of the axial e ow in the vortex is to decrease the vortex core radius and to increase the swirl on the suction side while the vortex core radius increases and the swirl decreases on the pressure side. The suction peak due to the vortex grows on the suction side and decreases on the pressure side both for the jet and the vortex.
