过流面积 meaning in English
area of passage
Examples
- Then it discusses the influence of electric parameters on the heating effect bases on an analysis of the result of the numerical simulation
在集肤效应作用下，电缆导体内部的有效过流面积减小，交流阻抗显著加大，其发热量也很大，井下电缆伴热加热技术就是利用这一原理来加热原油的。 - The simulation shows that the valve throttle area should be little as possible but must be more than 40 % of pipe section area ; when the total length of pipe is same , and the flow quantity is enough , pipe before primary valve should be thin and long , and the pipe after primary valve should be thick and short , the upriver and downriver small pressure fluctuation will badly lead to waterdrammer pressure rising , and spending more time in establishing pressure and flow quantity
仿真表明,阀门过流面积在满足大于管道截面积40 %的条件下应尽可能小;在管道总长一定并满足流量要求的条件下,主阀前应采取长而细的管道,阀后则应采用短而粗的管道;上下游微小的压力波动都会严重增大开关阀门引起的水击,并使压力、流量的建立需要更长的时间。 - First , the dynamic characteristics of pipe is simulated , the influence to waterhammer which is brought by the flow area of the valve , response time , the length of the pipe before and after the valve , the hydraulic pressure fluctuating in the trunk , and the high frequency pressure fluctuating in combustion chamber is analysed
首先对管道动态特性进行了仿真,分析了阀门过流面积、阀门作动时间、阀门前后管道的长度、贮箱压力波动以及燃烧室压力高频振荡等对管道动态特性的影响。
