In this paper we present a methodology for constructing accurate and efficient hybrid central-upwind (HCU) type schemes for the numerical resolution of a two-fluid model commonly used by the nuclear and petroleum industry. Particularly, we propose a method which does not make use of any information about the eigenstructure of the jacobian matrix of the model. The two-fluid model possesses a highly nonlinear pressure law. From the mass conservation equations we develop an evolution equation which...
In this paper we present a methodology for constructing accurate
and efficient (HCU) type schemes for
the numerical resolution of a two-fluid model commonly used by the
nuclear and petroleum industry. Particularly, we propose a method
which does not make use of any information about the
eigenstructure of the Jacobian matrix of the model.
The two-fluid model possesses a highly nonlinear pressure law.
From the mass conservation equations we develop an evolution
equation which describes how pressure...
