On the construction of upwind schemes for non-equilibrium transient two-phase flows

In this paper, a numerical method for the simulation of two-phase multi-dim ensional transient flows is presented. It is based on a finite volume expli cit scheme, and the recent density perturbation method. The computation of the upwinding is easy and we are able to handle high kinematic and thermal disequilibria in complex geometries for minor requirements. Numerical tests are provided showing the efficiency of our approach. (C) 2001 Elsevier Sci ence Ltd. All rights reserved.
