Progress in probability density function methods for turbulent reacting flows
TL;DR: Probability density function (PDF) methods have been widely used for modeling chemically reacting turbulent flows as discussed by the authors, where one models and solves an equation that governs the evolution of the one-point, one-time PDF for a set of variables that determines the local thermochemical and/or hydrodynamic state of a reacting system.
Journal ArticleDOI
Numerical simulation of the interaction between turbulence and radiation in reactive flows
TL;DR: The interaction between turbulence and radiation (TRI) in reactive flows has been demonstrated experimentally, theoretically and numerically, and results from the highly nonlinear coupling between fluctuations of radiation intensity and fluctuations of temperature and chemical composition of the medium.

TL;DR: A review of the opportunities and challenges surrounding the development of oxy-coal combustion models and discusses historical and recent advances in specific areas related to computational fluid dynamics (CFD), including char oxidation, radiation, pollutant formation and removal (Hg, NO x and SO x ), and the impact of turbulence as mentioned in this paper.

Importance of turbulence-radiation interactions in turbulent diffusion jet flames
Genong Li,Michael F. Modest +1 more
TL;DR: In this paper, the authors used the composition PDF method to study turbulence-radiation interactions in turbulent flames and found that TRI effects account for about 1/3 of the total drop in flame peak temperature caused by radiative heat losses.

Application of composition PDF methods in the investigation of turbulence–radiation interactions
Genong Li,Michael F. Modest +1 more
TL;DR: In this article, the composition probability density function (PDF) method is used to study radiating reactive flows, which is able to treat turbulence-radiation interactions in a rigorous way: many unclosed terms due to TRI in the traditional Reynolds-averaging process can be calculated exactly and all others can be accurately modeled by using the optically thin eddy approximation.

Turbulent jet diffusion flames
TL;DR: In this paper, the authors discuss the theoretical basis for diffusion flame analysis, with its implications on diffusion flame structure, and the limitations on the use of the two main reaction models, and address the question of the computation of the velocity and scalar fields focusing on the modeling of the turbulence under conditions of fluctuating and spatially varying density.

The nozzle-fluid concentration field of the round, turbulent, free jet
TL;DR: In this paper, the authors used the light-scatter technique to study the nozzle-fluid concentration field in an isothermal, turbulent, axisymmetric air/air free jet with the nozzle air marked by an oil smoke.
