A&a Manuscript No. Astronomy and Astrophysics the Consistent Multi--uid Advection Method

Simple modiications for higher-order Godunov-type diierence schemes are presented which allow for accurate advection of multi-uid ows in hydrodynamic simulations. The constraint that the sum of all mass fractions has to be equal to one in every computational zone throughout the simulation is fulllled by renormalizing the mass fractions during the advection… (More)
