This note discusses the relaxation process in an hybrid three-field two-phase flow model. The latter model aims at simulating the flow of a mixture of liquid water and its vapor, together with some non-condensable gas. Since the fast transient flow may involve shock waves, this model is well suited due to its main properties which are recalled in the first section.
