Simulation of motion of a fine particles flow in inclined closed space during aerodynamic flocking

The aim of the study is to determine the basic geometric dimensions and design parameters of the spray hopper, to obtain a mathematical model of the distribution and deposition of particle flow. The authors conducted experimental modeling of the flow, determining the concentration of particles and their deposition of the substrate, determined the influence of the geometric solution of the installation hopper on the main aerodynamic characteristic. The results of the work enable to quickly determine the distribution of particles in the flow, the density of the fluid, and other indicators affecting the characteristics of multilayer thermal insulation materials.
