抄録

An incompressible round compound jet issuing from a circular nozzle was simulated by a three-dimensional vortex blob method. The circular nozzle was composed of a source disc and vortex panels. The nascent vortex blobs were released from the edge of the nozzle in such a way that their circulation satisfies Kelvin's conservation law of circulation. The vortex rings released from the edge experienced vortex merging and developed three-dimensional structures with small-scale random structures. Effects of the limitation of maximum vorticity of the vortex blobs on the vortex structures were discussed. The large-scale vortical structure is fairly indendent of the limitation of maximum value of vorticity.
