摘要
使用纹影照相法观察了定容装置内从喷射阀喷出的天然气喷流的起动、发展过程。经画像处理得到的测定值表明 ,天然气喷流的贯穿距离与喷射时间的平方根成正比。这与从理论模型得到的计算结果是相当一致的 。
To verify the feasibility of non steady jet theoretical model of natural gas,a schlieren device was used to observe the starting and fully developed process of gas jet.The measurements processed with portrait processor show that the penetration of gas jet is proportional to the square root of time,this is very similar to the calculated results with the theoretical model,so non steady jet process of natural gas is revealed.
