摘要

摘要: 采用计算流体动力学方法,以LSGMF(Large-Scale Gas Mixing Facility)气体混合实验为参照,首先建立了LSGMF的三维物理模型和网格模型,然后对相关湍流模型的适用性进行了讨论,最后通过与实验数据对比,对所建立的计算模型进行了验证。结果表明,采用标准k-ε湍流模型计算求得的氦气浓度分布与实验数据较为吻合;目前所建立的CFX计算模型及方法基本上满足严重事故下氢气混合特性研究的需要,可以用于开展后续严重事故下多组分气体的扩散、流动、混合特性的研究。

Abstract: In this study, the CFX code is used to simulate the mixing phenomenon of hydrogen in the Large-Scale Gas Mixing Facility（LSGMF）. According to the experiment of hydrogen mixing conducted by AECL, a three-dimensional computational model of LSGMF is built and helium instead of hydrogen is injected into the facility. In order to adopt a suitable turbulence model, the standard k-ε, Shear Stress Transport and BSL Reynolds Stress turbulence model are discussed. Compared with the experiment data, it is found that the distribution of helium concentration when adopting the standard k-ε turbulence model is closest to the experiment results. In the end, through comparing the data of the helium distribution obtained by calculation with that obtained by experiment, it is found that the helium distribution is predicted well by the built computational model, which provides a good foundation for the further study of hydrogen mixing characteristics.
