Averkova, I. Logachev, K. Logachev] Hydrodynamic equations have been derived for a fl ux of particles free falling in an air-filled circular porous pipe which is surrounded by a cylindrical bypass chamber. In these equations, the reverse influence of air on the particles′ dynamics is disregarded. Numerical and analytical investigations of the derived equations made it possible to establish the regularities of change in the velocity of ejected air in the porous chute and in the pressure in the bypass chamber along the chute length as a function of the porosity of the walls and the dimensions of the chamber, and also on the ejection number. A rational range has been determined for ejection parameters ensuring the greatest reduction in the ejection volume due to the recycling of air.
