Abstract
The parallel and staggered obstacles which effected on flame shape in limited space by Compu-tational fluid dynamics software FLUENT were researched.Simulation size was 500 mm× 150 mm of two-dimensional rectangle space model,flame development process was calculated under four working conditions of two parallel obstacles,two staggered obstacles,three parallel obstacles and three stag-gered obstacles.The distance of the obstacles was 100 mm and the blocking rate was 0.5.K-epsilon Re-alizable turbulence model,P 1 radiation model and eddy dissipation model were used to simulate the flame propagation of gas explosion.Simulation results show that:flame turbulence has been found obviously in 10 ms and the larger area of preheating zone has appeared under the influence of staggered obstacles. Flame propagation process is closed to experiment,so the simulation results are reliable.The results provide the reference for the further numerical simulation study of gas explosion related content.关键词
