主 题:p-system two-phase fluid Hodograph transform Volterra equation
摘 要:We investigate a hyperbolic system of one-dimensional isothermal fluid with liquid-vapor phase *** refraction-reflection phenomena are intensively analyzed when elementary waves travel across the two-phase *** apply the characteristic method and hodograph transform of Riemann to reduce the nonlinear PDEs to a concise *** for the case of incident rarefaction wave,reduced linear equations are convenient to solve by Laplace *** an integral formula in wave interaction region is derived in this paper,instead of the hypergeometric functions solutions for non-isothermal polytropic *** is also observed that when incident waves travel from the vapor phase to the liquid phase,the refracted waves must be accelerated and move forward.
