Convective flux schemes for numerical solution of two-phase flows
Original language description
The main objective of this paper is the comparison of several numerical schemes for calculation of the convective numerical ?ux used in two-phase ?ow modeling and its impact on the quality of obtained numerical results. It is aimed at the dispersed two-phase ?ow modeling of immiscible compressible ?uids. The averaged Eulerian two ?uid model with one pressure ?eld in 1D is discussed, the ?ow is assumed to be inviscid without any interphase interaction. In-house computational was developed for the solution of the aforementioned problem. This software is based on the ?nite volume method. The convective numerical ?ux was approximated by the various suitable ?rst order schemes in order to damp instabilities, which can occur by using two-phase ?ow models. The code was tested on the water faucet benchmark. First, the volume fraction of gas was observed and compared with known analytical solution. This was done for two different states - the ?rst one captures the volume fraction shock change d
