Buoyancy effects on large-scale motions in convective atmospheric boundary layers: implications for modulation of near-wall processes
A number of recent studies have demonstrated the existence of so-called large-and very-
large-scale motions (LSM, VLSM) that occur in the logarithmic region of inertia-dominated …

Genuine compressibility effects in wall-bounded turbulence
M Yu, CX Xu, S Pirozzoli - Physical Review Fluids, 2019 - APS
Compressible wall-bounded turbulence is generally assumed to be devoid of genuine
compressibility effects, meaning that the effect of finite fluid dilatation is regarded as “small,” …
