基于计算流体力学的方法,构建了大规模液氢泛溢情况下的两相多组分流动的NavierStokes方程以及湍流封闭方程,建立了大规模液氢泛溢的数值模型。利用美国国家航空航天局于1981年完成的大规模液氢泛溢实验的数据进行了模型验证,并比较了模型在考虑和未考虑氧和氮相变2种情况下的数值计算结果,发现考虑了氧和氮相变的数值计算结果,相比于没有考虑氧和氮相变的数值计算结果,更加接近实验结果。 Based on computational fluid dynamics (CFD) method, two-phase multicomponent NavierStokes equation and turbulent closed-loop equations for large-scale liquid hydrogen spillover are constructed, and a numerical model for large-scale liquid hydrogen spillover is established. The model was verified by the data of large-scale liquid-liquid hydrogen spill experiments completed by NASA in 1981 and the numerical results of the model were compared with and without consideration of the oxygen and nitrogen phase transitions. The numerical results of the oxygen and nitrogen phase transitions are much closer to the experimental results than the numerical results without considering the phase transition of oxygen and nitrogen.
