A Kármán–Howarth–Monin equation for variable-density turbulence

CCK Lai, JJ Charonko, K Prestridge - Journal of Fluid Mechanics, 2018 - cambridge.org
We present a generalisation of the Kármán–Howarth–Monin (K–H–M) equation to include
variable-density (VD) effects. The derived equation (i) reduces to the original K–H–M …

Self-similarity criteria in anisotropic flows with viscosity stratification

L Danaila, L Voivenel, E Varea - Physics of Fluids, 2017 - pubs.aip.org
Variable-viscosity flows exhibit a faster trend towards a fully developed turbulent state since
fluctuations are produced at a larger amount. A legitimate expectation is that self-similarity to …
