| 摘 要： | 本文同时运用能耗率极值原理和重力理论研究了固液两相流在粗质颗粒时固相浓度的垂线分布,通过探讨能耗率极值原理对“非单向性”作用问题,进一步揭示了两相流运动的机理。计算结果与实测数据有较好的吻合。其研究方法、原理、步骤也极易推广到其它各种粒径的固相。

| Abstract: | In this paper, the extremity law of energy dissipation rate and the gravitational theory have been employed to study the vertical distribution of particle concentration of solid-liquid two-phase flow with coarse particles. The mechanism of two-phase flow motion is further revealed by means of employing the extremity law of energy dissipation for the study on the "non-unidirectivity" problem. The calculation results of particle distribution agree well with the experimental results. The investigation method, principle and procedure presented in this paper can readily be spread for solving the problem of solid phase with different particle diameters. |
