Study of Random Particle Interactions for Analysis of Diffusion Lengths in Turbulent Combustion Modelling

Turbulent combustion is commonly modelled using probability density function (PDF) methods; to close these methods, micro-mixing models are required: these are most commonly based on stochastic particle interactions. While it is standard practice for the turbulent diffusion coefficient to be...
