表面活性物质对液体晃动阻尼影响分析及计算

ANALYSIS AND NUMERICAL CALCULATION OF SLOSHING DAMPING CAUSED BY SUFFACTANT

  • 摘要: 对表面活性物质对液体晃动阻尼的影响进行了理论分析, 针对液体小幅自由晃动对表面活性物质耗散阻尼计算公式进行了推导. 在此基础上提出了结合液体晃动有限元计算的表面活性物质耗散阻尼的数值计算方法.通过将算例结果与实验值和理论分析结果进行比较, 数值方法的有效性得到了验证.

     

    Abstract: Surfactant is an important factor that causes sloshingdamping. In the present paper, the theory of sloshing damping caused bysurfactant is analyzed, and the calculation formula is derived. Then anumerical calculation method of surfactant sloshing damping is proposed onthe basis of FEM. The calculated value is compared with the theoretical andexperimental value, and the effectiveness of the numerical method isverified.
