| 摘 要： | 针对开敞空间可燃气云爆燃 (简称为UVCES)过程所产生的爆燃波为亚音速传播特点 ,对开敞空间可燃气云爆燃场进行数学求解。其中求解建立在小扰动波理论基础上 ,即从理想可压缩流体介质的基本运动规律出发 ,导出弱扰动情况下的波动方程并对球形坐标系下的波动方程进行积分求解 ,得到了具有普适意义的UVCES定性解。最后用中、小气量可燃气云 (乙炔 空气混合形成的非理想爆源 )进行爆燃实验 ,结果表明理论与实验吻合得很好。

| Abstract: | Aiming at the characteristic of deflagration wave occurring in course of UVCES transfers at a speed of sub sound,qualitative solution was gained.The integration of the agitation equation in the sphere coordinate is carried out based on the little agitation theory and the general solution of UVCES was obtained.And the contracted wave produced by the flame in the vapour cloud open to air is researched through model experiments.The result agrees well with the experimental data. |
