Experimental Study on Influence of Open/closed-end Conduit on Flame Intensity
The flame propagation velocity and the flame temperature was Proposed to represent the flame intensity. The influence of open/closed-end conduit on flame intensity in different work conditions were studied, such as lubricate, sticking heat-insulated materials in ignite side, etc. The experimental conduit is rectangular in cross section, measuring 80mm×80mm in width. The research result shows that when the gas explosion, the influence of open/closed-end conduit on flame intensity in gas explosion initial stage is relatively little. After that, the flame acceleration degree, the acceleration range, the flame propagation velocity maximum, in open-end conduit is greater than that in closed-end conduit, but the flame temperature at the back part in open-end conduit is obviously less than that in closed-end conduit. The reason is that the reflected waves suppress the flame propagation, and produce the oscillation burning, increase the burning rate.
