STOCHASTIC MODELS OF PARTICLE MOTION IN A TURBULENT FLOW AND THEIR APPLICATION FOR CALCULATING INTERNAL FLOWS
K. N. Volkov UDC 532.529:536.24 This paper considers issues connected with the construction and numerical realization of stochastic models of motion and scattering of condensed impurity particles in a turbulent flow based on the integration of a Langevin-type equation. The proposed model is used to calculate the turbulent flow of a low-concentration gas suspension in a channel with permeable walls. Calculations are performed for various values of the injection rate, sizes of particles, and the conditions of their introduction into the channel. D. F.
