项目摘要

This work has been performed on purpose to establish a practical CFD method for the numerical simulation of high-speed submerged water jets as well as the hydrodynamic design of jet nozzles. The main results can be summarized as follows: (1) A compressible mixture flow method based a simplified estimation of bubble cavitation is established. (2) A modification on the eddy viscosity of cavitating flow is proposed considering the effect of bubble expanding and contracting. (3) Numerical simulation of turbulent activating jets issuing form submerged orifice nozzle were carried out and the reliability of present method has been verified experimentally. (4) A new sheathed orifice nozzle is developed and its property has been evaluated via visualization experiment.
本工作旨在建立一种实用的CFD方法,用于高速浸没水射流的数值模拟和喷嘴的水动力设计。主要研究结果如下:(1)建立了一种基于气泡空化简化估算的可压缩混合流计算方法。(2)提出了考虑气泡膨胀和收缩影响的空化流动涡粘性修正方法。(3)对潜孔喷嘴喷出的湍动射流进行了数值模拟,并通过实验验证了该方法的可靠性。(4)研制了一种新型护套孔板喷嘴,并通过可视化实验对其性能进行了评价。
