Assess the impact of a more comprehensive physical model

Assess how incorporating the full energy equation and alternative driving mechanisms, as in the simulations of compressible turbulence reported by JDSJFM2021, affects the two Mach-number-dependent dissipative-anomaly branches and their asymptotic behavior.

Background

The present study considers an isothermal equation of state and purely solenoidal forcing. The authors contrast this setup with earlier simulations that included the full energy equation and different ways of driving the turbulence.

The comparison is relevant because thermodynamic evolution and forcing type may alter the production mechanisms, spatial organization, and Reynolds-number dependence of total, solenoidal, and dilatational dissipation. The paper explicitly states that the consequences of this more comprehensive physical model cannot be evaluated within the present work.
