关于水下管道气体泄漏的试验研究

Experimental Study on Gas Leakage of Underwater Pipeline

通过特定管道的水下气体泄漏试验,观察气泡羽流的上升过程和与自由表面接触时的扩散现象,监测管道内气体的流量和气泡羽流扩散前的直径,分析水深、喷口孔径、孔前气压和管道内气体流量等因素对气泡羽流直径的影响,为数值模拟研究提供可靠数据,对实际工程具有一定的参考价值。

Through gas leakage experiment of the specific underwater pipeline, we can ohserve the rising process of bubble plume as well as the diffusion of bubble plume when it contacts free surface, monitor gas flow within the pipeline and the diameter of bubble plume before it diffuses, analyze the influence on the diameter of bubble plume by water depth, diameter of nozzle, nozzle pressure and gas flow within pipeline, which will provide reliable data for numerical simulation research, and be referred to in many projects.
