Feasibility study on application of SAS turbulence model in numerical simulation of gas cloud explosion
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.
