Numerical Analysis of Turbulent Combustion in a Model Swirl Gas Turbine Combustor

Journal of Combustion, 2016
Turbulent reacting flows in a generic swirl gas turbine combustor are investigated numerically. Turbulence is modelled by a URANS formulation in combination with the SST turbulence model, as the basic modelling approach.

Effect of V-cut on the performance of a longitudinal vortex generator using CFD [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2022
Computational analysis is conduct to investigate the comparative study between V-cut vortex generator and without Vcut vortex generator at different spacing lengths. Water is the working fluid, and the Reynolds number is varying in the range of 300 to 1,

Simulations of stellar convection, pulsation and semiconvection [PDF]

, 2010
We report on modelling in stellar astrophysics with the ANTARES code. First, we describe properties of turbulence in solar granulation as seen in high-resolution calculations.

Large-scale magnetic flux concentrations from turbulent stresses [PDF]

, 2009
In this study we provide the first numerical demonstration of the effects of turbulence on the mean Lorentz force and the resulting formation of large-scale magnetic structures.

Generative modeling of turbulence

Physics of Fluids, 2022
We present a mathematically well-founded approach for the synthetic modeling of turbulent flows using generative adversarial networks (GAN). Based on the analysis of chaotic, deterministic systems in terms of ergodicity, we outline a mathematical proof that GAN can actually learn to sample state snapshots from the invariant measure of the chaotic ...

On the Relative Effect of Underwater Optical Turbulence in Different Channel Conditions

IEEE Access
This paper presents a simulation framework for modelling optical underwater turbulence in conjunction with absorption and scattering. Using this technique, the channel is evaluated in two ways: the turbulent statistics in different channel conditions ...
