摘要
基于欧拉-拉格朗日方程的拉格朗日离散相模型,并建立颗粒的受力模型,对超临界水膜反应器内的气固两相流特性进行数值模拟。模拟并分析了颗粒直径、入口速度对超临界水膜反应器内的颗粒运动规律、分布特性以及颗粒接近多孔璧的参数的影响,并且分析了超临界水膜反应器中一定直径的颗粒的流体随体性。对研究和优化超临界水膜反应器的气固两相流特性具有一定的指导意义。
Based on the Lagrangian discrete phase model of the Euler-Lagrangian equation,and the force model of the particles is established.The gas-solid two-phase flow characteristics in the supercritical water film reactor are numerically simulated.The effects of particle diameter and inlet velocity on the particle motion and distribution characteristics in the supercritical water film reactor and the parameters of the particles near the porous crucible were simulated and analyzed,and the fluid of a certain diameter particle in the supercritical water film reactor was analyzed.This article has a certain guiding significance for the research and optimization of gas-solid two-phase flow characteristics of supercritical water film reactors.
