本文探讨了低浓度水平管道液固两相流的相似问题。根据两相流的液相和固相运动方程、能量方程、连续性方程、悬浮速度方程、和沉降速度方程及颗粒的悬浮和推移条件等关系,得出两相流的一系列相似模化条件。根据这些条件提出了液固两相流模型管道试验的计算原则,最后用已有的实验资料对上述计算原则进行校验。对其结果进行评议分析。为了验证能用准则关系式统一表达已有的大部分学者提出的计算公式。本文列表对其作了对照。它说明在两相流研究中运用相似理论的可行性及其实用性。为了说明能用准则关系式表达其宏观物理模型的一致性.本文提出了一个新的相似准则:Du
This paper explores the similarities of liquid-solid two-phase flow in low-concentration horizontal pipelines. According to the relationship between the liquid and solid phase motion equations, the energy equation, the continuity equation, the suspension velocity equation and the settling velocity equation of the two-phase flow and the suspension and displacement conditions of the particles, a series of similar modeling conditions . According to these conditions, the calculation principle of pipeline test for liquid-solid two-phase flow model is proposed. Finally, the above calculation principle is verified by the existing experimental data. Evaluate the results. In order to verify that the standard relation formula can be used to unify the calculation formula proposed by most scholars. This article lists its contrast. It shows the feasibility and practicality of applying similar theory in the study of two-phase flow. To illustrate the consistency of the macroscopic physical models can be expressed by the relational criteria, a new similarity criterion is proposed in this paper: Du
