The Piston Problem Of The Euler Equations For Van Der Waals Gas

This paper is devoted to the piston problem of the Euler equations for isentropic modified Van der Waals gas.The modified Van der Waals gas state equation agrees with the reality,which was constructed by Maxwell using area equal principle.Then the system transforms mixed type into hyperbolic type.By the characteristic analysis methods,the piston problem of the Euler equations for the modified Van der Waals gas is studied,and the motions of gas caused by pushing and pulling the piston are shown.
