Abstract
Combustion is an important practical application of low speed, variable density flows and information on the statistical properties of a scalar field and the interaction between scalar fluctuations, θ, and their dissipation rate, χ, is needed to quantify the mixing processes. For example, it has been shown by Bilger (1980) that the reaction rate of a turbulent diffusion flame is a function of the joint probability density function, pdf, between θ and χ. Also, Liew et al. (1984) have shown that flame extinction in the laminar flamelet regime may be modelled in terms of the cumulative probability density function, cdf, of the values of χ that correspond to a family of strained flamelets, which exceeds a quenching value χq.
