Sticky issues in turbulent transport. [PDF]

Ann Henri Poincare, 2022
We investigate the role of partial stickiness among particles or with a surface for turbulent transport. For the former case, we re-derive known results for the case of the compressible Kraichnan model by using a method based on bi-orthogonality for the expansion of the propagator in terms of left and right eigenvectors.

Multi-fidelity information fusion for turbulent transport modeling in magnetic fusion plasma [PDF]

Scientific Reports
Maintaining the high-temperature and pressure conditions required for sustained nuclear fusion is challenging due to the turbulent transport that naturally occurs in the plasma. Developing reliable models for turbulent transport is essential for progress

Turbulent Flow Structures Over a Gobi Surface and Their Impact on Aeolian Sand Transport

Geophysical Research Letters, 2023
Here, we present the results of turbulent flow structures and their influence on aeolian sand transport over gobi surfaces based on quadrant analysis. The results show that the classified turbulent structures over gobi accounted for 43%–44% of the time ...

Non-Equilibrium Turbulent Transport in Convective Plumes Obtained from Closure Theory

Atmosphere, 2023
The non-equilibrium property of turbulence modifies the characteristics of turbulent transport. With the aid of response function formalism, such non-equilibrium effects in turbulent transport can be represented by the temporal variation of the turbulent
