Abstract

Numerical simulation on a vortex ring generated by an impulsive started disc is studied. Commercial CFD software is used for the numerical simulation. Modelling results are compared with previous experimental data. The circulation, vortex core position and symmetric breaking time are discussed at two different velocities. Results show that a larger velocity leads to a greater vortex ring circulation, a shorter developing time for occurring asymmetry phase comparing with a smaller velocity.
