气垫式调压室最小稳定断面推导

Inference on the minimal stable cross section of air cushion surge chamber

气垫式调压室最早于1973年在挪威德利伐(Driva)水电站建成投入运行,目前国内已经有建成并投入运行的采用气垫式调压室的水电站。本文对气垫式调压室最小稳定断面计算进行推导,以供参考。

In 1973, the air cushion surge chamber was first used in Driva hydropower station of Norway. At present, air cushion surge chamber are used in China. This paper calculated the minimal stable cross section of air cushion surge chamber, for reference.
