The scale-up method for the hydrodynamic processes in a sorbent layer using CFD simulation with the Ergun's equation-based models

Abstract

The prospects of ion-selective treatment for the liquid radioactive waste volume reducing are shown. The main problems of the hydrodynamics scale-up and ion-exchange equipment design are outlined. The review of the methods of the hydrodynamic processes it packed bed and multiphase flow simulation methods based on Navier-Stokes equations is presented. The packed bed columns engineering calculation methods based on the Ergun's equation are shown. The possibility and prospects of the CFD simulation with Ergun's equation-based models based using for the ion-exchange equipment designing scale-up problem solving are shown. The main aspects of the packed bed hydrodynamics mathematical models' formulation for one-component and multicomponent flows in a fixed bed and a moving bed of an ion exchange sorbent are presented. The based on the Ergun's equation and the multiphase mixture model mathematical model formulation for the hydrodynamics in the sorbent bed is shown. © 2021 Author(s).
