Please help!!

My PhD supervisor is convinced that Discontinuous Galerkin Methods will work for Roe averaged multiphase matrices. But I am sure it will not work due to the non-conservative pressure terms. So I am kind of stuck. As an alternative I'm trying to find the matrices equations for simplified multiphase flow - specifically non-homogeneous equilibrium model or homogeneous equilibirum model.

Does anyone know a paper/book chapter where these models are shown?
Specifically I'm looking for the matrix equations in the form U_{t} + A U_{x} = S.

Thanks in advance. Any help would really be much appreciated.
