The statistical concept of coarse particle motion in a turbulent pipe flow
Abstract
On the basis of modern theory of stochastic processes the closed equation for probability function (PDF) velocity and coordinates of particles in inhomogeneous turbulent flow has been derived. The gaseous phase turbulent pulsations are approximated by the random Markov process with fixed correlation function. The system for the averaged velocity and pulsation motion of dispersed phase are presented. The boundary conditions for the equation accounting particlewall interaction are given. The equations have been solved and the deposition rate, intensity of normal velocity of particles, particle concentration profiles, averaged velocity of dispersed phase have been obtained. Predictions are in a good agreement with measurements.
