  1. Based on the thoroughly review and summary in the progress history of the multiphase flows researching in recent fifty years, the thesis was made an advanced discussion on the wide foreground of the multiphase flows " study and application, and clarified some concept of multiphase flows " study. take gas - solid two - phase flows for example, the thesis discussed and classified the theoretical model of multiphase flows " study, that is continuum model, discrete particle model and pseudo particle model, and made a deep and detail discussion on the foundation, advantage and disadvantage about the three physical model. the thesis considered that all the mathematics models of the multiphase flows " study are based on the three physical models

    本文在系統、全面地回顧和總結近五十年來多相流研究發展歷史的基礎上,進一步論述了多相流研究和應用的廣闊前景;澄清了多相流研究中存在的一些模糊概念;以氣固兩相流研究為例,對多相流研究的各種理論模型進行了系統的析、歸納和,從而把氣固兩相流研究的物理模型其刻劃的尺和屬性為三,即:連續介質模型( continuummodel ) 、離散顆模型( discreteparticlemodel ) 、流體擬顆模型( pseudoparticlemodel ) ,並對三物理模型賴于存在的基礎、長處和存在的問題進行了深入的析、討論;同時指出,多相流研究的各種數學模型都是建立在以上三物理模型的基礎上的,從而對各種數學模型的實質、優缺點和今後發展方向有了清晰的了解。
