Non-universality and dissipative anomaly in compressible magnetohydrodynamic turbulence
MULTISCALE DYNAMICS IN MAGNETIZED TURBULENCE II ORAL
spa-solar and heliospheric physics | 13 december 2024
Minping Wan, Cheng Li, Yan Yang, William H. Mattha...
Dissipative anomaly states that ε, the rate of turbulent energy dissipation away from boundaries, remains finite as viscosity tends to zero. As a basi...
