But for the continuous jet which velocity gradient is not linear, it has not only one virtualorigin.
但对于非线性速度分布的连续射流,存在的虚拟原点不是唯一的。
2
The radius variation of the jet in the motion process is deduced based on the virtualorigin concept.
基于虚拟原点概念推导了运动过程中射流径向尺寸变化规律。
3
The classical penetration equation based on the virtualorigin theory can well describe the penetration behaviour of the continuous jet with linear velocity distribution.
