Abstract

The invention relates to a system for testing solid-liquid two-phase flowing with an adjustable inclined pipe angle, and belongs to the technical field of two-phase flowing experiment tests. Accordingto the system, a closed solid-liquid two-phase flowing circulation loop is formed by a fixed pipeline, a dredge pump, an inlet flexible elbow, a transparent glass pipe, an inclined test pipeline, anoutlet flexible elbow, a rigid elbow, a flexible pipeline, a steering flexible elbow and a horizontal extending pipe, wherein a solid particle dosing system is arranged above the fixed pipeline, a supporting platform is arranged under the horizontal extending pipe; a lifting hydraulic cylinder is arranged under the supporting platform to support platform lifting adjustment. The system has functions of testing hydraulic loss and pressure change of solid-liquid two-phase flowing in pipelines having different inclined angles and observing solid-liquid two-phase flowing form in pipelines having different inclined angles and the like, a platform for studying the solid-liquid two-phase flowing mechanism can be provided, and the system can be applied to deep studying of hydraulic characteristicsand internal status of solid-liquid two-phase flowing.

Description

technical field [0001] The invention belongs to the technical field of two-phase flow experiments and tests, and in particular relates to a solid-liquid two-phase flow test system with an adjustable inclined pipeline angle. Background technique [0002] At present, with the development of ports, waterways, water conservancy and coastal city construction, the engineering conditions involved in dredging enterprises are also more complicated. For dredging construction enterprises, the level of technology has become an important issue directly related to the survival and development of enterprises. The research on solid-liquid two-phase flow technology is an important part of dredging technology and the core technology in dredging engineering, which determines the production efficiency, project schedule and project cost. Solid-liquid two-phase flow technology is a technology based on semi-theory and semi-experience, and its research results are heavily dependent on experimental...
