Numerical simulation of low Mach number liquid gas flows

International audience This work is devoted to the numerical simulation of liquid-gas flows. The liquid phase is considered as incompressible, while the gas phase is treated as compressible in the low Mach number approach. We present a model and a numerical method aimed at the computation of such tw...

Description
Summary:International audience This work is devoted to the numerical simulation of liquid-gas flows. The liquid phase is considered as incompressible, while the gas phase is treated as compressible in the low Mach number approach. We present a model and a numerical method aimed at the computation of such two-phase flows. The numerical model uses a lagrangian front-tracking method to deal with the interface. To validate our model, we present preliminary results in the 1D case of a heated enclosure, inside which a liquid zone is inserted between two gaseous zones.
