The flame length of a plume in incompressible cross-flow is analyzed and the results are compared with those obtained in a chemically reacting water tunnel experiment. It is argued that the axial vortex pair in the flow arises from the plume momentum normal to the free stream, the momentum flux being equivalent to the impulse from the buoyant force.

化学反应的横向羽状流

分析了不可压缩错流中烟流的火焰长度，并将其结果与化学反应水隧道实验中获得的结果进行了比较。有人认为，流动中的轴向涡流对是由垂直于自由流的羽流动量产生的，动量通量等于浮力产生的冲量。
