| 摘 要： | 气泡流经过静态混合器的压降问题涉及到舰船动力系统性能的好坏。在分析了气泡平均驰豫时间的基础上,结合k ε湍流模型,利用平衡流模型模拟静态混合器内形成的稀疏湍流气泡流,得到了混合器内两相流流场。空气—水系统的压力降实验表明,计算流体力学模拟能够很好地预测SMV型静态混合器内气泡流的压降,是静态混合器设计的有效手段。

Numerical Simulation and Experimental Research on Pressure Drop of Gas -Liquid Two Phase Flow in Static Mixer |

| Abstract: | The pressure drop of the bubble flow in static mixer is related to the performance of the ship power system.Based on the analysis of the average particulate relaxation time of the bubbles,and combined with the k-ε turbulence module, the homogeneous flow model is used to simulate the dilute turbulent bubble flow in static mixer,and the flow field of two phase flow is achieved.The pressure drop experiments of the air—water system indicate that computational fluid dynamics simulation can predict the pressure drop of the bubble flow in SMV static mixer perfectly and is an effective method to design the static mixer. |
