Entropic Regularization of the Discontinuous Galerkin Method in Conservative Variables for Three-Dimensional Euler Equations.

The entropic regularization of the conservative stable discontinuous Galerkin method (DGM) in conservative variables for three-dimensional Euler equations is constructed through the use of a special slope limiter. This limiter ensures the fulfillment of the three-dimensional analogs of the monotonicity conditions and a discrete analog of the entropic inequality. The developed method is tested on a three-dimensional model problem of a Taylor–Green vortex. [ABSTRACT FROM AUTHOR]
