While significant increase in turbulent burning rate in lean premixed flames of hydrogen or hydrogen-containing fuel blends is well documented in various experiments and can be explained by highlighting local diffusional-thermal effects, capabilities

Forest fires can be classified into two regimes, depending on Byram convective number NC: a plume-dominated and wind-driven regime. This classification is often based on two-dimensional (2D) studies without considering flame front structures, and is

RANS Simulations of Statistically Stationary Premixed Turbulent Combustion Using Flame Speed Closure Model

Autor: Salman Verma, Andrei Lipatnikov, Ehsan Yasari

Publikováno v: Flow, Turbulence and Combustion. 94:381-414

Turbulent Flame Closure (TFC) and Flame Speed Closure (FSC) models of the influence of turbulence on premixed combustion are applied to RANS simulations of five sets of experiments with (i) highly turbulent, oblique, confined ONERA flames under eleva
