Viewed on a hydrodynamic scale, flames in experiments are often thin so that they may be described as gasdynamic discontinuities separating the dense cold fresh mixture from light hot burned products. The original model of flame discontinuity was due to Darrieus and Landau. In addition fluid dynamical equations, consists speed relation describing evolution surface, jump conditions across surface which relate variables two sides surface. Darrieus–Landau predicts, contrast observations,...
Nonlinear phenomena can often be well described using probability density functions (pdf) and pdf transport models. Traditionally, the simulation of requires Monte-Carlo codes based on Lagrangian “particles” or prescribed assumptions including binning techniques. Recently, in field combustion, a novel formulation called stochastic-field method solving Eulerian fields has been proposed which eliminates necessity to mix techniques assumptions. In present work, for first time is applied...
The stability of a steadily propagating planar premixed flame has been the subject numerous studies since Darrieus and Landau showed that in their model flames are unstable to perturbations any wavelength. Moreover, instability was shown persist even for very small wavelengths, i.e. there no high-wavenumber cutoff instability. In addition Darrieus–Landau instability, which results from thermal expansion, analysis diffusional indicates may exhibit cellular pulsating instabilities as...
The extraction of statistical information from bubbly flow experiments is crucial for numerical studies. Knowledge regarding probability distributions particularly relevant in cases where a model relying solely on the use mean values would lead to inaccurate results. As such, existing studies have focused evaluating spatial and local histograms void fraction, bubble density, size. However, traditional box-counting method, employed by various studies, results inconsistencies when deriving...
