| 摘 要： | This paper mainly designs artificaial boundary conditions for “vortex in cell“ method in solving two-dimensional incompressible inviscid fluid under two conditions:on is with periodical initial value in one direction and the other with compact supported initial value.To mimic the vortex motion,Euler equation is transformed into vorticity-stream function and the technique of vortex in cell is applied incorporating with the artificial boundary conditions.
