An Antidissipative Transport Scheme on Unstructured Meshes for Multicomponent Flows

International audienceA new numerical method called Vofire is described here. It can be used for integrating transport equations approximated on general meshes in any dimension. The algorithm relies on a piecewise constant reconstruc-tion of an unknown in each cell, where the reconstructed function varies only in the directions orthogonal to the velocity. This allows to design a non-dissipative and maximum preserving scheme for the transport of char-acteristic functions. It is then incorporated in a Lagrangian scheme with remeshing for the computation of multi-component compressible flows
