КОМПЬЮТЕРНАЯ МОДЕЛЬ ОСАЖДЕНИЯ ПОЛИДИСПЕРСНЫХ СУСПЕНЗИЙ В ПРОТОЧНЫХ СИСТЕМАХ

Abstract

A computer model of the deposition of polydisperse suspensions has been developed. The model describes the process of deposition of a polydisperse suspension in flow systems. A new method for calculating the distribution of the dispersed phase at the outlet of the flow apparatus has been presented. The technique is based on the calculation of boundary deposition curves for various fractions of a dispersed mixture. Based on the new model, a computer program has been developed to calculate the evolution of deposition fronts, which is important for calculating the kinetics of deposition of polydisperse suspensions in natural processes and industrial flow devices. The new method for calculating the boundary deposition curves also allows us to propose a simple and effective method for calculating changes in the fractional composition of the slurry at the outlet of the flow area, as well as the dynamics of the deposition fronts and the sediment surface, both along the height of the reactor and along the longitudinal coordinate of the flow apparatus. In this paper, effective software for the implementation of a new calculation methodology has also been developed and tested for the first time.
