A statistical model for the calculation of the frequency of turbulent collisions of particles of arbitrary density
L. I. Zaichik, V. M. Alipchenkov Joint Institute for High Temperatures, Russian Academy of Sciences, Moscow
Abstract:
A statistical model is given for determining the kernel of collisions of inertial particles (droplets, bubbles) in the entire range of variation of the density ratio between the dispersed and continuous phases. The model is based on the assumption that the joint probability density function of velocities of continuous medium and particles is a Gaussian distribution. The ranges of variation of bubble sizes are determined, in which the decisive part is played by the “inertial” and “spatial” collision mechanisms.
