摘要:
为揭示立式混合机内复合推进剂药浆混合过程中的安全机制及混合效果，采用计算流体动力学（CFD）方法，建立了均质单相流体稳态模型。针对12组不同药浆黏度（331.342~1 260.216 Pa·s）与桨叶转速（42.50~85.00 r/min）的工况，系统模拟并分析了压力、温度、剪切应力、扭矩及混合流场等关键参数的变化规律。结果表明：黏度、转速与压力、剪应力及扭矩均显著正相关; 在1 260.216 Pa·s、 85.00 r/min高参数组合下,最大剪应力达6.867 MPa，远超3.180 MPa安全阈值;而温度升高有限（最高61.66 ℃）。表明该工况下热累积风险有限，机械剪切作用更值得关注。识别出7种高风险工况，主要集中于较高黏度和较高转速条件。通过量化流动死区占比、流场覆盖率及轴向循环效率评估混合效果发现，提高转速可显著改善混合的均匀性与效率，但会同步增加安全风险。进一步通过平衡指数耦合安全与混合性能，明确了兼顾安全与效率的最佳操作窗口。可为推进剂混合工艺优化提供依据。
