Simple Advection Scheme for Material Interface

OSTI ID:15006111
We introduce a new simple advection scheme for capturing multi-material interfaces. A material interface is tracked by solving a scalar transport equation of the volume of fluid. The method is developed by modifying the Hyper-C flux limiter and it does not require material interface reconstruction. A new single step unsplit advection scheme is developed by including corner flux monotonically. The algorithm is designed to minimize the necessary mixed zones as well as to preserve sharp and stable interfaces. Numerical tests show improvements compared to other existing methods such as Tipton's method.
