We prove that this system verifies conservation properties together with a maximum principle regarding the volume fraction of the gas. Our main result is that the barotropic version of this system is locally in time well-posed in H$^s$. %G English %2 https://hal.science/hal-03881187v1/document %2 https://hal.science/hal-03881187v1/file/newmodel.pdf %L hal-03881187 %U https://hal.science/hal-03881187
