Collisional transport across the magnetic field in drift-fluid models [PDF]

, 2016
Drift ordered fluid models are widely applied in studies of low-frequency turbulence in the edge and scrape-off layer regions of magnetically confined plasmas.

Turbulence models of gravitational clustering [PDF]

, 2011
Large-scale structure formation can be modeled as a nonlinear process that transfers energy from the largest scales to successively smaller scales until it is dissipated, in analogy with Kolmogorov's cascade model of incompressible turbulence.

Comparative study on related models of propeller cavitation numerical simulation

Zhongguo Jianchuan Yanjiu, 2023
ObjectiveThe purpose of this paper is to study the effects of cavitation models on the simulation of full-scale propeller cavitation. MethodsThe minimum rotational speed of the propeller required for cavitation is predicted by the Bernoulli equation, and

Two-equation modeling of turbulent rotating flows [PDF]

, 2005
The possibility to take into account the effects of the Coriolis acceleration on turbulence is examined in the framework of two-equation eddy-viscosity models.

Modeling Profiles of Micrometeorological Variables in a Tropical Premontane Rainforest Using Multi‐Layered CLM (CLM‐ML)

Journal of Advances in Modeling Earth Systems, 2021
This study updates the multi‐layered Community Land Model (CLM‐ml) for hillslopes and compares predictions from against observations collected in tropical montane rainforest, Costa Rica.

Self-Organization of Vortex Length Distribution in Quantum Turbulence: An Approach from the Barabasi-Albert Model [PDF]

, 2006
The energy spectrum of quantum turbulence obeys Kolmogorov's law. The vortex length distribution (VLD), meaning the size distribution of the vortices, in Kolmogorov quantum turbulence also obeys a power law.

Ensemble Kalman method for learning turbulence models from indirect observation data [PDF]

Journal of Fluid Mechanics, 2022
In this work, we propose using an ensemble Kalman method to learn a nonlinear eddy viscosity model, represented as a tensor basis neural network, from velocity data.

The effect of slip on the development of flow separation due to a bump in a channel based on a two-fluid turbulence model [PDF]

E3S Web of Conferences
In the paper, two-fluid turbulence model simulations were used to calculate the flow of a statistically two-dimensional turbulent boundary layer over a hump.
