摘要
A closed equation for the probability density function of the velocity of particles is obtained in explicit form using the functional-differentiation method, taking into account the non-uniformity of the velocity field of the carrying turbulent flow. A system of continual equations of the balance of mass, momentum and second moments of the velocity pulsations of the dispersed phase is constructed. The result is compared with published solutions for a uniform layer. (C) 1997 Elsevier Science Ltd. All rights reserved.
