为系统探究不同相间力模型对数值模拟结果的影响，本文基于开源平台OpenFOAM，采用欧拉－欧拉双流体模型对气液两相流动开展瞬态数值模拟，分析不同相间力关联式的预测特性，并通过与实验数据及参考结果对比验证了各模型的准确性。研究覆盖低、中、高三种雷诺数工况，对应不同气液流态，重点揭示曳力、升力、壁面润滑力及湍流耗散力等模型对气泡运动行为与径向空泡份额分布的影响机制。结果表明，并不存在适用于全流动工况的通用标准模型，相间力模型的选取需结合具体气泡流态与雷诺数范围。在低雷诺数条件下，曳力模型主导气泡迁移过程；在高雷诺数工况下，升力模型对相分布形态起主导作用，可使空泡峰值由壁面区域向主流区转移；湍流耗散力则促使径向空泡份额分布趋于均匀。此外，升力、壁面润滑力与湍流耗散力之间的耦合作用显著提升了径向相分布的预测精度。模拟结果确定了不同雷诺数区间内的最优相间力模型组合。通过系统分析各相间力在不同雷诺数下的作用机理，本文提出了相间力模型选用策略框架，为复杂气泡流数值模拟中的多相流模型配置提供了理论依据与优化思路。研究进一步证实，在低含气率条件下，即便忽略气泡聚并与破碎效应，竖直绝热气泡流的相分布仍可得到有效预测，为多相流模型简化提供了可行参考。

To systematically investigate the effects of different interphase force models on numerical simulation results, transient numerical simulations of gas-liquid two-phase flow were carried out by using the Euler-Euler two-fluid model based on the open-source platform OpenFOAM. The prediction performances of various interphase force closures were analyzed, and the accuracy of each model was validated by comparison with experimental data and reference results. The study covered low, medium, and high Reynolds number conditions, corresponding to various gas-liquid flow regimes. It focused on revealing the mechanisms of drag, lift, wall lubrication, and turbulent dispersion forces governing bubble dynamics and radial void fraction distribution. The results show that there exists no universal model valid for the entire range of flow conditions, and the choice of interphase force models depends on the specific bubbly flow regime and Reynolds number range. At low Reynolds numbers, the drag force model dominates the bubble migration process. At high Reynolds numbers, the lift force model plays a dominant role in phase distribution patterns, shifting the void fraction peak from the wall region to the core flow region. The turbulent dispersion force tends to homogenize the radial void fraction distribution. Furthermore, the coupling effect among lift force, wall lubrication force and turbulent dispersion force significantly improves the prediction accuracy of radial phase distribution. The simulation results determine the optimal combinations of interphase force models within different Reynolds number ranges. Based on a systematic analysis of the mechanisms of each interphase force under various Reynolds numbers, this paper proposes a strategic framework for selecting interphase force models, which provides a theoretical basis and optimization guidance for the multiphase flow model configuration in numerical simulations of complex bubble flows. The study further confirms that, under low gas fraction conditions, the phase distribution of vertical adiabatic bubbly flow can be accurately predicted even if bubble coalescence and breakup effects are neglected, which provides a feasible reference for the simplification of multiphase flow models.
