1) Velocity ratio
流速比

Tests show that the flow pattern,the jet s depth of penetration and the extent of the affected region remain the same if the velocity ratio is kept constant;while increasing the velocity ratio causes the jet s penetration depth to extend,flow deflection to diminish and flow along the manifold s wall to reduce.
在相同的流速比下,流型和射流穿透深度、影响区域基本相同;随着流速比的增加,射流穿透深度增大,偏斜减小,沿主管管壁流体减少。
