Characterization of mesoscopic turbulent transport events with long-radial-range correlation in DIII-D H-mode plasmas
R. Hong, T. L. Rhodes, Y. Ren +6
A dimensionless collisionality scan has been performed in H-mode plasmas on DIII-D tokamak, with detailed measurements of intermediate-to-high wavenumber turbulence using Doppler b…
Observation of Long-Radial-Range-Correlation in Turbulence in High-Collisionality High-Confinement Fusion Plasmas
R. Hong, T. L. Rhodes, P. H. Diamond +6
We report on the observation of spatially asymmetric turbulent structures with a long radial correlation length in the core of high-collisionality H-mode plasmas on DIII-D tokamak.…
How Turbulent Jets Can Disperse Virus Clouds in Poorly Ventilated Spaces
Justin Tahmassebpur, Patrick H. Diamond
We show that enhanced turbulent mixing can be used to mitigate airborne COVID-19 transmission by dispersing virus-laden clouds in enclosed, poorly ventilated spaces. A simple syste…
Generation of momentum transport in weakly turbulent -plane magnetohydrodynamics
R. A. Heinonen, P. H. Diamond, M. F. D. Katz +1
Magnetohydrodynamic (MHD) turbulence on a -plane with an in-plane mean field, a system which serves as a simple model for the solar tachocline, is investigated analytically and…
Potential Vorticity Transport in Weakly and Strongly Magnetized Plasmas
Chang-Chun Chen, Patrick H. Diamond, Rameswar Singh +1
Tangled magnetic fields, often coexisting with an ordered mean field, have a major impact on turbulence and momentum transport in many plasmas, including those found in the solar t…
Turbulence model reduction by deep learning
R. A. Heinonen, P. H. Diamond
A central problem of turbulence theory is to produce a predictive model for turbulent fluxes. These have profound implications for virtually all aspects of the turbulence dynamics.…
