ДИНАМИКА ВЗВЕШЕННОГО СЛОЯ С ПОЛИДИСПЕРСНЫМИ ЧАСТИЦАМИ В ПНЕВМОСМЕСИТЕЛЯХ НЕПРЕРЫВНОГО ДЕЙСТВИЯ

Abstract

The article presents a technique that describes the dynamics of a suspended layer with polydisperse particles in the working volume of the displacement chamber of a continuous air mixer. This technique was obtained on the basis of studies conducted by the authors of the article, taking into account experimental data obtained by other scientists. This material generalizes the approach to numerical modeling of a suspended layer with particles of various dispersity (for example, for dry building mixtures) and density. The dependences of the layer boundary, its porosity and velocity parameters on particle diameters, geometrical parameters of the mixing chamber and other technological quantities affecting the suspended layer inside the chamber are established. The text of the article presents an algorithm for calculating the mechanics of a suspended layer, which has proven itself in numerical modeling of the layer with high calculation accuracy, which was later confirmed by the required amount of experimental data.
