Mach-number-dependent dissipative anomaly in isothermal compressible turbulence
Shadab Alam, Georgy Zinchenko, Christoph Federrath +1
Using a comprehensive set of three-dimensional, high-resolution direct numerical simulations, we investigate the existence of a dissipative anomaly in isothermal, homogeneous, isot…

Extending the Duchon-Robert framework for anomalous dissipation to compressible fluid flows
Georgy Zinchenko, Jörg Schumacher
Anomalous dissipation, the persistence of a finite mean kinetic energy dissipation as the Reynolds number tends to infinity, occurs in flows with sufficiently spatially rough veloc…

Local precursors to anomalous dissipation in Navier-Stokes turbulence: Burgers vortex-type models and simulation analysis
Georgy Zinchenko, Vladyslav Pushenko, Joerg Schumacher
Anomalous dissipation is a dissipation mechanism of kinetic energy which is established by a sufficiently spatially rough velocity field. It implies that the rescaled mean kinetic…
