The linear-eddy approach for modelling molecular mixing in turbulent flow involves
stochastic simulation on a one-dimensional domain with sufficient resolution to include all …

The transport equation for the joint probability density function of velocity and scalars is
shown to provide a good basis for modeling turbulent reactive flows. As in the equation for …

The linear-eddy model of turbulent mixing represents a spatially developing flow by
simulating the time development along a comoving transverse line. Along this line, scalar …

A new approach to chemistry modelling for large-eddy simulation of turbulent reacting flows
is developed. Instead of solving transport equations for all of the numerous species in a …

Considering the importance of the effects of turbulent mixing on chemical reactions, it is
surprising that the statistical theory is less than 20 years old. Turbulent motion is often …

The objectives of this paper are (i) to establish analytically some important features of the
scalar diffusion process in turbulence and (ii) to derive a closure model for this process in …

A method is presented whereby the fast chemistry reaction, Fuel+(r) Oxidizer→(1+ r)
Product, may be modeled in the context of a large eddy simulation (LES). The model is …
