One-dimensional turbulence (ODT) simulations of a spatially developing planar shear layer are used to obtain the probability density function (PDF) of the concentration of a passive scalar. An asymmetry of the PDF with respect to transverse location

One-dimensional turbulence is a stochastic simulation method representing the time evolution of the velocity profile along a notional line of sight through a turbulent flow. In this paper, the velocity is treated as a three-component vector, in contr

Molecular dynamics simulations using the Lennard-Jones energy potential are compared with continuum solutions of reaction and diffusion in a dilute gas. The reaction model is a passive one in which high-energy bath atoms create a species, at dilute c

A premixed flame within a turbulent flow exhibits a decreasing enhancement of fuel consumption rate with increasing turbulence intensity, an effect known as the bending effect. Denet has shown that flow time correlations may be one cause of the bendi

Molecular dynamics of two- and three-dimensional liquids undergoing a homogeneous adiabatic expansion provides a direct numerical simulation of the atomization process. The Lennard-Jones potential is used with different force cutoff distances; the cl

A premixed flame, propagating away from a point ignition source into an unlimited domain displays an increasing flame speed after the flame size has grown beyond a transition radius. Experiments by Gostintsev et al are described by the relation R = R

Three-dimensional turbulence simulations which include three different mean directions of passive flame propagation are analyzed for the isotropic nature of the flame shape, as given by the fluctuations in the G scalars which determine the passive Hu

Flame propagation through an array of vortices was studied with a model which incorporated the variation of the local burning velocity with stretch. Assuming incompressible flow, the mean burning velocities were calculated and compared to those of th

Flame propagation into a swirling flow allows the creation of burnt gas vorticity which may enhance the forward motion of the flame. This baroclinic push on the flame differs from the axial pressure model suggested by Chomiak (1976). In particular, t

A flame ball growing into a turbulent mixture exhibits a speed which is proportional to its size - this effect is a consequence of the distorted flame surface: the inner flame regions “push” the outer regions, the magnitude of this velocity depen
