orifice diameter meaning in English

压缩喷嘴孔径

The bubble diameter increases with air flow rate , air pressure , orifice diameter and the solution depth , and decreases with the orifices number and liquid viscosity
在静态水模拟实验条件下获得了液体表面气泡直径预测模型。
The research indicates that the orifice jet in mixing conditions has many different points from the pipe jet . focusing on the jet ejected from the orifices of different diameters and lengths , this paper studies the orifice jet when the fluid upstream of the orifices is in mixing conditions . the main purpose is to qualitatively study the effect of orifice diameters and lengths on the spread of the jet
射流是在工程实际中广泛存在的一种流动现象，喷嘴出口的流动状态对射流的发展有很大的影响，前人对射流的研究主要集中于喷嘴前流体是完全发展管流的情形，本文研究了全混状态下的板式射流，研究结果表明全混状态下的板式射流具有很多不同于管射流的特点。
