SAS模型是一种新兴的CFD湍流模型。为了探究SAS模型在瓦斯气云爆炸问题上的可行性,对预混气云进行点火,与标准k-ε模型的模拟结果进行对比。结果发现SAS模型所得的模拟结果在气云爆炸发展过程、正负超压值和正负超压到达时间均与标准k-ε模型相近,验证了SAS模型的可靠性。本研究为SAS模型在工程上的应用提供一定的参考。

SAS model is a new CFD turbulence model. In order to explore the application feasibility of SAS model in gas cloud explosion, the premixed gas cloud is ignited and the simulation results are compared with those of k-ε standard model. The results show that the simulation results obtained by SAS model are similar to those of the k-ε standard model in the development process of gas cloud explosion, the positive and negative overpressure values and the arrival time of positive and negative overpressure, which verifies the reliability of SAS model. This study provides some reference for the application of SAS model in engineering.
