Hybrid flux-splitting schemes for a common two-fluid model
Steinar Evje,Tore Flåtten +1 more
TL;DR: Results from test cases show that the aim of this paper is to construct hybrid FVS/FDS schemes which properly combine the accuracy of FDS in the resolution of sharp mass fronts and the robustness of FVS which ensures stability under stiff conditions.

FLICA-4: a three-dimensional two-phase flow computer code with advanced numerical methods for nuclear applications
TL;DR: Toumi et al. as discussed by the authors developed a finite volume numerical method for 3D two-phase flow calculations based on an extension of Roe's approximate Riemann solver to define convective fluxes versus mean cell quantities.

An upwind numerical method for two-fluid two-phase flow models
TL;DR: In this article, an upwind numerical method for a six equation two-fluid model is presented based on a linearized Riemann solver, which has proved to be stable on nonstaggered grids and capable of generating accurate nonoscillating solutions for two-phase flow calculations.
