J un 2 00 9 Chapter 1 Two-fluid barotropic models for powder-snow avalanche flows

Abstract

In the present study we discuss several modeling issues of powder-snow avalanche flows. We take a two-fluid modeling paradigm. For the sake of simplicity, we will restrict our attention to barotropic equations. We begin the exposition by a compressible model with two velocities for each fluid. However, this model may become non-hyperbolic and thus… (More)
