We first construct an approximate Riemann solver of the HLLC-type for the Baer-Nunziato equations of compressible two-phase flow for the "subsonic" wave configuration. The solver is fully nonlinear. It is also complete, that is, it contains all the characteristic fields present in the exact solution of the Riemann problem In particular, stationary contact waves are resolved exactly We then implement and test a new upwind variant of the path-conservative approach, such schemes are suitable for solving numerically nonconservative systems Finally, we use locally the new HLLC solver for the Baer-Nunziato equations in the framework of finite v
