# A hierarchy of non-equilibrium two-phase flow models

@article{Linga2019AHO, title={A hierarchy of non-equilibrium two-phase flow models}, author={Gaute Linga}, journal={ESAIM: Proceedings and Surveys}, year={2019} }

We review and extend a hierarchy of relaxation models for two-phase flow. The models are derived from the non-equilibrium Baer–Nunziato model, which is endowed with relaxation source terms to drive it towards equilibrium. The source terms cause transfer of volume, heat, mass and momentum due to differences between the phases in pressure, temperature, chemical potential and velocity, respectively. In the context of two-phase flow models, the subcharacteristic condition implies that the sound…
