First is free flow in which the density of traffic is low enough to allow vehicles to travel at the maximum speed allowed.
首先是畅通无阻，交通密度足够低，使得车辆能以最高时速行驶。
Through the numerical simulation, the distribution of those parameters such as speed, pressure of the free jet and impinging jet flow is obtained, also the position of shocks.
通过数值计算，得到了喷嘴出口自由射流与冲击射流情况下的流体速度、压力等参数分布情况，及这两种流场中的激波位置。
Absorption by double tower, with higher efficiency, higher speed, meet the standard of free-flow.
设计双塔循环吸收，吸收效率更高、吸收速度更快，可达到直排要求。
