TL;DR: In this paper, a numerical study of the gas-powder flow in a typical Lapple cyclone is presented, where the effects of particle size and gas velocity on separation efficiency are quantified and the results agree well with experiments.

TL;DR: In this paper, a numerical study of the gas-solid flow in a gas cyclone is carried out by use of the combined discrete element method (DEM) and computational fluid dynamics (CFD) model where the motion of discrete particles phase is obtained by DEM which applies Newton's equations of motion to every individual particle and the flow of continuum fluid by the traditional CFD which solves the Navier-Stokes equations at a computational cell scale.

TL;DR: In this paper, the authors used the Reynolds stress model (RSM) to simulate the turbulent flow of gas, and the outcome is used in the simulation of particle motion by adopting the stochastic Lagrangian particle tracking model (LPT).

TL;DR: In this paper, the authors proposed a method to solve the problem of chemical engineering science using the concept of Chemical Engineering Science (CES) and applied it to chemical engineering applications.

TL;DR: In this paper, a series of metal rods and metal blades are inserted in the typical Lapple cyclone separator to reduce the intensity of the inner vortex, and the results show that when the length of the metal blades is less than the boundary between the inner and outer vortexes, that is, the outer vortex remains unchanged and inner vortex is destroyed partly, the separation efficiency remains constant and the pressure drop significantly decreases.
