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

Multiscale Turbulent Transport [PDF]
, 2020 Turbulent transport is currently a prominent and ongoing investigation subject at the interface of methodologies from theory to numerical simulations and experiments, and it covers several spatiotemporal scales. Mathematical analysis, physical modelling, and engineering applications represent different facets of a classical, long-standing problem that ...

Optimizing Stellarators for Turbulent Transport [PDF]
Physical Review Letters, 2010 Up to now, the term "transport-optimized" stellarators has meant optimized to minimize neoclassical transport, while the task of also mitigating turbulent transport, usually the dominant transport channel in such designs, has not been addressed, due to the complexity of plasma turbulence in stellarators.

Scalar Transport Characteristics Near the Turbulent/Non-Turbulent Interface in a Reactive Jet Flow
气体物理Turbulent/non-turbulent interface (T/NTI) layer separates the turbulent and non-turbulent regions. The study of T/NTI is helpful to deepen the understanding of mass transfer between turbulent and non-turbulent regions.

Modelling of turbulent swirling flows [PDF]
, 2004 This thesis investigates the predictability of non-reacting and reacting anistropic turbulent, swirling flows using popular turbulence models with a robust numrical procedure. The performance of these turbulence models is assessed and compared against

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.
