folding edge meaning in Chinese

弯折边缘

In this paper , according to the need of developing new style column , new style fixed - valve tray - rectangular fixed - valve tray with fold edges and common rectangular fixed - valve tray were studied from experiments and cfd simulation
本文针对开发塔设备新类型的需要，从实验和cfd模拟两方面对新型的固定阀塔板-带折边矩形固定阀塔板以及普通的矩形固定阀塔板进行了研究。
At first , in the process of experiments , it were measured that dry plate pressures drop and point pressures in the flow fields around the single fixed - valve and double fixed - valves under different velocities by using of pitot tube . after that point pressure was transformed to point velocity , two dimensions flow plane of flow fields around fixed - valve were plotted to observe the difference between of the fixed - valve tray with fold edges and the common rectangular fixed - valve tray on the distributions of flow fields and pressures , to provide comparisons and refer - rence for cfd simulation
在实验中，利用测速管等仪器对在不同速度下的单阀和双阀固定阀周围的流场进行了点压力测量，然后把点压力转化为点速度后绘出固定阀周围流场的二维流线图，同时测定了塔板的干板压降，来考察新型固定阀带折边后对流场分布和压降的影响，为随后的数值模拟提供对比和依据。
