Energetic particle acceleration in a 3D magnetic field reconnection model: a role of MHD turbulence [PDF]
, 2000 The role of MHD turbulence in the cosmic ray acceleration process in a volume with a reconnecting magnetic field is studied by means of Monte Carlo simulations.

Mathematical Methodology and Metallurgical Application of Turbulence Modelling: A Review
Metals, 2021 This paper focusses on three main numerical methods, i.e., the Reynolds-Averaged Navier-Stokes (RANS), Large Eddy Simulation (LES), and Direct Numerical Simulation (DNS) methods. The formulation and variation of different RANS methods are evaluated.

Modelling of natural and bypass transition in aerodynamics
EPJ Web of Conferences, 2014 Most of transition models are proposed for modelling of the bypass transition common in the internal aerodynamics especially in turbomachinery where free stream turbulence is the dominant parameter affecting the transition onset.

A SPH Model for Incompressible Turbulence [PDF]
Procedia IUTAM, 2015 A coarse-grained particle model for incompressible Navier-Stokes (NS) equation is proposed based on spatial filtering by utilizing smoothed particle hydrodynamics (SPH) approximations. This model is similar to our previous developed SPH discretization of NS equation ({\it Hu X.Y. & N.A. Adams, J. Comput.

Turbulent Magnetohydrodynamic Elasticity: I. Boussinesq-like Approximations for Steady Shear [PDF]
New Astron. 10 (2004) 133-144, 2002 We re-examine the Boussinesq hypothesis of an effective turbulent viscosity within the context of simple closure considerations for models of strong magnetohydrodynamic turbulence. Reynolds-stress and turbulent Maxwell-stress closure models will necessarily introduce a suite of transport coefficients, all of which are to some degree model-dependent ...

Neon seeding effects on two high-performance baseline plasmas on the Joint European Torus
Nuclear Fusion, 2023 We present the JETTO-QuaLiKiz-SANCO fully predictive modelling of two JET-ILW high-performance baseline plasmas, a Ne seeded shot and an equivalent unseeded one.
