摘要:
为了研究方形狭长密闭空间内障碍物对瓦斯爆炸的影响，建立密闭方管模型，采用数值模拟的方法研究球体障碍物不同的直径及排列方式对火焰及冲击波传播规律的影响。研究结果表明：有障碍物的密闭方管模型内火焰的传播速度及压力均明显大于无填充密闭方管模型；同位排列的密闭方管模型内，随着球体障碍物直径的减小，火焰的传播速度呈先增后减的变化，压力上升速率的最大值约为无填充密闭方管模型的60倍；错位排列的密闭方管模型内，压力上升速率的最大值约是同位排列模型的100倍。
Abstract:
In order to study the influence of obstacles on gas explosion in the square narrow enclosed space, a model of enclosed square tube was established, and the influence of spherical obstacles with different diameters and arrangement modes on the propagation laws of flame and shock wave were studied by using the numerical simulation method. The results showed that both the flame propagation speed and pressure in the enclosed square tube model with the obstacles were significantly greater than those of the enclosed square tube model without the obstacles. In the enclosed square tube model with the alignment arrangement, the flame propagation speed increased first and then decreased with the decrease of the diameter of spherical obstacles, and the maximum pressure rising rate was about 60 times of that of the enclosed square tube model without the obstacles. In the enclosed square tube model with the interval alignment arrangement, the maximum pressure rising rate was about 100 times of that of the enclosed square tube model with the alignment arrangement.
