Optimized acoustic bias plus rank-1 entropy correction in characteristic reconstruction improves efficiency and removes the need for contact-discontinuity detectors in compressible CFD.
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.
