| Abstract: | A numerical study on the interaction between a planer shock wave and a vortex ring is performed by solving the unsteady Euler equations time accurately.The initial data is obtained by assuming a Gaussian vorticity distribution in the cross section of the vortex ring,and an instantaneous solenoidal velocity field with a homogeneous entropy is employed at this moment for simlicity.The time advancing is performed by using second order Range Kutta scheme and the NND scheme.Two categories of the shock vortex interaction,that is,reverse and catching up,are examined at different parameters. |
