    摘要:

    通过计算流体动力学数值模拟与模型试验相结合的方式,对耙吸挖泥船环保阀减少空气进入溢流筒的机理和作用进行相关研究。将模型试验与数值模拟的结果进行对比,验证气液两相流数值模型的准确性。进行不同进口流量、不同环保阀角度时的计算,获得进口流量、泥舱内液面高度、环保阀角度之间的相关性数学描述,据此建立环保阀的控制策略。建立叠加式溢流筒的数值模型,分析其在减少溢流上的效果。

    Abstract:

    Through the combination of numerical simulation of computational fluid dynamics and model test, the relevant research on the mechanism and function that the environmental protection valve of trailing suction hopper dredger reduces the air entering the overflow cylinder are conducted. The model test and numerical simulation results are compared to verify the accuracy of gas liquid two phase flow numerical model. The calculation of different inlet flow rates and different environmental protection valve angles is made to obtain the mathematical description of correlation among inlet flow rate, hopper liquid level, and environmental protection valve angle, and according to such a description, the control strategy of environmental protection valve is established. The numerical model of stacked overflow cylinder is established and its effect on reducing the overflow is analyzed.
