Finite volume methods for complex hyperbolic systems

Participants: P. Helluy, L. Quibel (EDF)

This year we have developed a Lattice Boltzmann scheme able to treat really complex and tabuled EOS (Equation Of State) for compressible multiphase flows (two and three phases). This new scheme have been implemented in the PyOpenCL Patapon. Additionally, in order to perform realistic simulations of such situations, we have also proposed a code based on a model that can handle both the thermodynamical disequilibrium between liquid and vapor and complex equations. This code is based on a relaxation scheme which is the best compromise between accuracy and stability.
