This paper presents a computational algorithm for Yu. M. Davydov's large-particle method, adapted for calculating the dynamics of monodisperse inert gas suspensions in an axisymmetric cylindrical geometry. The mathematical model is based on the equations for conservation of mass, momentum, and energy for a two-phase gas-solid particle medium, accounting for interfacial friction and heat transfer. The author describes in detail the three stages of the Eulerian-Lagrangian cycle (Eulerian, Lagrangian, and final), and provides difference schemes for calculating mass fluxes and intermediate parameter values. The algorithm is designed for modeling complex flows in process plants and natural processes.
