摘　　要：针对有限空间内的氨泄漏情况,采用FLUENT软件选择合适的模型对不同泄漏压力下有限空间内氨气扩散进行模拟分析。通过对模拟与现场试验分别得到的氨气质量浓度变化数据进行比较,两者趋势吻合,最大误差不超过15%,认为该有限元模型可以为工程提供参考。Aiming at accident of ammonia leakage in finite space, a appropriate physical model was established using FLUENT, by which the ammonia diffusion process with different leakage pressure was analyzed./3y comparing variation curves of ammonia concentration obtained by the experimental platform and FLUENT, the result shown that the trends of them were coincided, and the maximum error was 15%. It is considered that the finite element model can provide reference for engineering.
