A 2D unstructured multi-material Cell-Centered Arbitrary Lagrangian–Eulerian (CCALE) scheme using MOF interface reconstruction

We present an original Cell-Centered Arbitrary Lagrangian–Eulerian (CCALE) strategy using the Moment Of Fluid (MOF) interface reconstruction devoted to the numerical simulation of two-dimensional multi-material compressible fluid flows on general unstructured grids. Our methodology is assessed through several demanding two-dimensional tests and comparison with Volume Of Fluid (VOF) interface reconstruction. The corresponding numerical results provide a clear evidence of the robustness and the accuracy of this new scheme.
