The paper develops a wave-structure-based multidimensional upwinding algorithm for compressible multiphase flows that tailors reconstruction schemes to acoustic, vorticity, and entropy waves plus interfaces to improve accuracy and reduce artifacts.
An adaptive reconstruction method combines a contact discontinuity detector with THINC for phasic densities and central schemes for tangential velocities to capture material interfaces more sharply in viscous compressible multicomponent flow simulations.
