Flow Aeration at Stepped Cascades

摘要

The report presents experimental data for two flow regimes: nappe flow andskimming flow. New experimental data were obtained using a 25-m long stepped channel with a 3.4-degree slope. Flow was nappe flow without hydraulic jump: i.e., supercritical all along the cascade. The stepped cascade flow exhibited three-dimensional patterns: shock waves and sidewall standing waves.
