Calculation of the disintegration of any break in the flow of a two-speed two-phase incompressible

https://doi.org/10.15514/ISPRAS-2014-26(5)-9

Abstract

It is proposed to modify the Godunov computation method for modeling the gas-liquid bubble flow. To have a numerical scheme, effect of the coefficients - at the differential constituents in the hydrodynamic averaged equations set - on the hydrodynamic wave properties is discussed. Sspecific solution of Riemann problem has been obtined.
