Abstract

Numerical simulation of multi-component flows is a challenging task. It requires dealing with mathematical models, numerical solution techniques, uniformity and nonuniformity of the physical and thermodynamic properties of the flow component and the dynamic changes of the interfaces. In this contribution a numerical application is developed to solve a pressure non-equilibrium multi-component model. The numerical solution is based on a finite volume scheme and the interface is treated as a diffuse zone with a small controlled thickness. Since each flow component has its own pressure, a pressure relaxation procedure is considered during the solution. The code is verified against benchmark tests in one and two dimension flows. The results show very good agreement with the reference data, which proves the capabilities of the developed numerical tools.
