A computational investigation of the finitetime blowup of the 3D incompressible Euler equations based on the Voigt regularization
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.
