| Abstract: | In the present paper,the accuracy of severalcomparative typical deterministic vortex methods(DVM)and their parameter condi-tions are studied by using a model problem of the diffusion of a Rankine Vortex in unbounded viscous flow field.The numerical results show thatthe accuracy of DVMs are higher than those of random vortex method. |
