Title Convection Regularization of High Wavenumbers in Turbulence ANS Shocks.

Abstract This manuscript discusses the recent results in the research project on inviscid regularization techniques with emphasis on applications to compressible gas flows. It is well-established that general systems of quasilinear, first-order hyperbolic PDEs exhibit finite-time blowup of smooth solutions, thus restricting well-posedness of classical solutions in short- time. For instance, with conservation laws, one must generally seek global-in- time solutions in a larger class of discontinuous solutions. Further physically motivated admissibility conditions are placed in order to obtain the uniqueness and stability of such solutions.
