摘      要：The fluid flows in a variable cross-section duct are nonconservative because of the source ***,the Riemann problem and the interactions of the elementary waves for the compressible isentropic gas in a variable cross-section duct were *** this paper,the Riemann problem for Chaplygin gas flow in a duct with discontinuous cross-section is *** elementary waves include rarefaction waves,shock waves,delta waves and stationary waves.
