Asymptotic behaviour at the wall in compressible turbulent channels

Akanksha Baranwal et al.

Summary: This study investigates the effects of compressibility on the near-wall asymptotic behavior of turbulent fluxes using a large direct numerical simulation (DNS) database, finding that the behavior of compressible turbulent flow near walls differs from incompressible flow even when mean density variations are considered. As Mach number increases, turbulent fluxes containing wall-normal components exhibit a decrease in slope due to increased dilatation effects, with Ity approaching its high Mach number asymptote at lower Mach numbers than other fluxes.

Fully developed anelastic convection with no-slip boundaries

Chris A. Jones et al.

Summary: Anelastic convection at high Rayleigh number in a plane parallel layer with no-slip boundaries is studied, deriving energy and entropy balance equations to develop scaling laws for heat transport and Reynolds number. The appearance of an entropy structure allows for explicit forms of these scaling laws based on the Rayleigh number, Prandtl number, and temperature ratio. Different scaling laws are found depending on whether viscous dissipation primarily occurs in the boundary layers or in the bulk, with numerical simulations comparing theoretical predictions up to a Rayleigh number of 10^7.

Does dissipative anomaly hold for compressible turbulence?

John Panickacheril John et al.

Summary: A systematic study on dissipative anomaly in compressible turbulence was conducted using direct numerical simulations. It was found that the classical incompressible scaling does not apply to total dissipation in compressible turbulence. The solenoidal dissipation follows the same scaling as incompressible turbulence, while the dilatational part exhibits dissipative anomaly. Based on these findings, new criteria for energy cascade were proposed.
