A multiphase model for compressible flows with interfaces, shocks, detonation waves and cavitation. (English)
0 references
A compressible multiphase unconditionally hyperbolic model is proposed which is able to deal with a wide range of applications. The arising difficulties are reviewed for flows involving fluid interfaces, homogeneous mixtures, boiling and cavitating flows, and a solution strategy is developed for any of these applications. This model does not need a mixture equation of state and provides thermodynamic variables for each phase. This is important for detonation modelling. Also, it is conservative regarding the mixture, even at the interfaces. This provides accurate energy and temperature computations. A variety of test problems has been considered, and results are shown graphically.
