A splitting method for the isentropic Baer-Nunziato two-phase flow model
Résumé
In the present work, we propose a fractional step method for computing approximate
solutions of the isentropic Baer-Nunziato two-phase flow model. The scheme relies on an operator
splitting method corresponding to a separate treatment of fast propagation phenomena due to the
acoustic waves on the one hand and slow propagation phenomena due to the fluid motion on the
other. The scheme is proved to preserve positive values of the statistical fractions and densities.
We also provide two test-cases that assess the convergence of the method.
