| 摘 要： | 为研究空化泡溃灭阶段的数值仿真,本文以格子Boltzmann方法为基础,采用改进作用力引进格式,对改变力学稳定性条件相关参数进行优化。通过最优参数提取,提高该多相格子Boltzmann模型密度比,从而最大程度保证热力学一致性及模型稳定性。并通过共存密度曲线对比及误差值计算,确定了参数的最优值。基于改进伪势格子Boltzmann模型对空泡溃灭进行建模,并将计算结果和实验结果对比,验证了空泡溃灭模型的有效性,对实际运用有一定的指导意义。

| Abstract: | The bubble collapse is modeled using an improved pseudopotential lattice Boltzmann model. An improved forcing scheme is adopted and the parameter relating to the mechanical stability condition is optimized to achieve the thermodynamic consistency and model stability. The optimum parameters are verified by calculating the numerical coexistence curves and errors. By comparing the results with experiments, the reliability of the model is validated. It is demonstrated that the pseudopotential lattice Boltzmann model is an alternative tool for bubble collapsing modeling. |
