GENERALIZATION OF THE RIEMANN METHOD FOR SOLVING THE PROBLEM OF WAVE PROPAGATION IN A SEMI-INFINITE GAS PIPELINE BY A QUADRATIC
Keywords:
quadratic law of resistance, semi-infinite gas pipeline, pulse propagation, quasi-one-dimensional equations for pipeline transportation of real gas, finite-difference method, computational experiment.Abstract
A mathematical model of the problem of pulse propagation in a semi-infinite gas pipeline was compiled by expressing the pressure drop by a quadratic law of resistance and by the local component of the gas inertia force in the law of conservation of momentum and using the law of conservation of mass in a one-dimensional formulation. The model repeats the Riemann problem but takes into account the frictional resistance force
