A computational investigation of the finitetime blowup of the 3D incompressible Euler equations based on the Voigt regularization
Abstract
We report the results of a computational investigation of two blowup criteria for the 3D incompressible Euler equations. One criterion was proven in a previous work, and a related criterion is proved here. These criteria are based on an inviscid regularization of the Euler equations known as the 3D EulerVoigt equations, which are known to be globally wellposed. Moreover, simulations of the 3D EulerVoigt equations also require less resolution than simulations of the 3D Euler equations for xed values of the regularization parameter α > 0. Therefore, the new blowup criteria allow one to gain information about possible singularity formation in the 3D Euler equations indirectly; namely, by simulating the betterbehaved 3D EulerVoigt equations. The new criteria are only known to be suficient for blowup. Therefore, to test the robustness of the inviscidregularization approach, we also investigate analogous criteria for blowup of the 1D Burgers equation, where blowup is wellknown to occur.

Using the generalized variable formulation of the Euler equations of fluid dynamics, we develop a numerical method that is capable of simulating the flow of fluids with widely differing thermodynamic behavior: ideal and real gases can be treated with the same method as an incompressible fluid. The welldefined incompressible limit relies on using pressure primitive or entropy variables. In particular entropy variables can provide numerical methods with attractive properties, e.g. fulfillment of the second law of thermodynamics. We show how a discontinuous Galerkin finite element discretization previously used for compressible flow with an ideal gas equation of state can bemore »

Entropybased viscous regularization for the multidimensional Euler equations in lowMach and transonic flows
We present a new version of the entropy viscosity method, a viscous regularization technique for hyperbolic conservation laws, that is wellsuited for lowMach flows. By means of a lowMach asymptotic study, new expressions for the entropy viscosity coefficients are derived. These definitions are valid for a wide range of Mach numbers, from subsonic flows (with very low Mach numbers) to supersonic flows, and no longer depend on an analytical expression for the entropy function. In addition, the entropy viscosity method is extended to Euler equations with variable area for nozzle flow problems. The effectiveness of the method is demonstrated usingmore » 
A Cartesian grid projection method for the incompressible Euler equations in complex geometries
Many problems in fluid dynamics require the representation of complicated internal or external boundaries of the flow. Here the authors present a method for calculating timedependent incompressible inviscid flow which combines a projection method with a Cartesian grid approach for representing geometry. In this approach, the body is represented as an interface embedded in a regular Cartesian mesh. The advection step is based on a Cartesian grid algorithm for compressible flow, in which the discretization of the body near the flow uses a volumeoffluid representation. A redistribution procedure is used to eliminate timestep restrictions due to small cells where themore »
