摘要
本文针对船舶管路系统中阀门引起的流噪声问题,以不同类型、不同规格的船用阀门的声学性能为研究对象,建立流道的几何模型,借助于计算流体力学通用软件Fluent通过计算其内部流体通道中的流噪声,并通过定量对比确定其优劣。研究结果表明,球阀相比其他类型阀门声学性能更优,该方法可为阀门选型提供一定的理论依据。
In this paper,in view of the characteristics of the flow-noise,created by marine valves of piping systems,the acoustic performances of marine valves on different types and specifications are researched.After establishing the flow geometric model,the flow-noise in the internal fluid channel is accomplished with the common Computational Fluid Dynamics software Fluent.Finally we determine its advantages and disadvantages through quantitative comparison.The results show that the ball valve has better acoustic performance than other types of valves,this method can provide a certain theoretical basis for the valve selection.
