The Impact of Turbulence on Physics of the Geomagnetic Tail
Frontiers in Astronomy and Space Sciences, 2021 There is a vast amount of evidence that suggests that the geomagnetic tail is like a turbulent wake behind an obstacle. Large-scale vortices in the wake are able to generate turbulent transport that takes place both along the plasma sheet, in the X and Y

Statistical Conservation Laws in Turbulent Transport [PDF]
Physical Review Letters, 2001 We address the statistical theory of fields that are transported by a turbulent velocity field, both in forced and in unforced (decaying) experiments. We propose that with very few provisos on the transporting velocity field, correlation functions of the transported field in the forced case are dominated by statistically preserved structures.

Estimation of Turbulent Triplet Covariances for Bora Flows
Fluids, 2021 Bora is a strong or severe, relatively cold, gusty wind that usually blows from the northastern quadrant at the east coast of the Adriatic Sea. In this study bora’s turbulence triplet covariances were analysed, for the first time, for bora flows.

Connecting dispersion models and wall temperature prediction for laminar and turbulent flows in channels [PDF]
, 2012 In a former paper, Drouin et al. (2010) proposed a model for dispersion phenomena in heated channels that works for both laminar and turbulent regimes. This model, derived according to the double averaging procedure, leads to satisfactory predictions of ...

Numerical Simulation on the Scalar Transport in Rotating Channel Turbulence
气体物理, 2023 Passive scalar transport in channel turbulence with spanwise rotation is of relevance to many engineering applications. A systematical study on this problem was conducted based on direct numerical simulations. The Reynolds number defined by wall-friction

Effects of swirl on intermittency characteristics in turbulent non-premixed flames [PDF]
, 2012 Swirl effects on velocity, mixture fraction and temperature intermittency have been analysed for turbulent methane flames using LES. The LES solves the filtered governing equations on a structured Cartesian grid using a finite volume method, with ...
