| Abstract: | This paper is 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. Sexuality. This article has a certain guiding significance for the research and optimization of gas-solid two-phase flow characteristics of supercritical water film reactors. |
