| 中文摘要: |
| 采用欧拉-拉格朗日坐标相结合的方法研究稠密气固两相流动对气固两相流的发展具有重大意义,本文详细介绍了目前国内外采用此方法研究稠密气固两相流的研究现状,重点介绍了DSMC算法、环境粒子法、DEM软球法及这些方法的应用,分析了存在的问题,并提出了目前可行的发展方向。 |
| 英文摘要: |
| The current activities of dense particle-gas two-phase flow technology in China and abroad are reviewed in this paper,including the Direct Simulation of MonteCarlo Method(DSMC),the neighborhood interactive probability method and the Discrete Element Method(DEM).These methods and their applications in China and abroad are introduced and compared in detail.The existent problems are analyzed.Finally,the developing tendency in dense particle-gas two-phase flow modeling is proposed. |
