Description

technical field [0001] The invention relates to the field of density flow model tests, in particular to a particle-driven variable density flow stable outflow device. Background technique [0002] Density flow is ubiquitous in nature and in practical engineering. Observing hyperpycnal flow in the field has great uncertainty and requires a lot of manpower and material resources. Therefore, laboratory tank experiments have become one of the main methods for scholars in various fields to explore hyperpycnal flow. According to the different generation mechanism, the hyperpycnal flow can be divided into: component-driven hyperpycnal flow and particle-driven hyperpycnal flow. Among the published patent schemes, various schemes for hyperpycnal flow tests have been given at home and abroad. For example, salt water is a typical composition-driven hyperpycnal flow, and particle-driven hyperpycnal flow is generally prepared with sediment, but sediment Due to the sedimentation charact...

Problems solved by technology

Among the published patent schemes, various schemes for hyperpycnal flow tests have been given at home and abroad. For example, salt water is a typical component-driven hyperpycnal flow, and particle-driven hyperpycnal flow is generally prepared with sediment, but sediment Due to its own weight, it has the characteristics of sedimentation, which will inevitably cause the initial concentration to be unstable, so the stable outflow of sediment density flow has always been a technical problem
