涡流区 meaning in Chinese
eddy zone
vortex cavity
Examples
- Numerous and extensive cavities retard the turbulent mixing process .
多而大的涡流区延迟了扰动的混合过程。 - Numerous and extensive eddy cavities retard the turbulent mixing process .
多而大的涡流区延迟了扰动的混合过程。 - If the injection period is extended long enough, the effects of isolated eddy cavities are neutralized .
如果喷注时期延续得足够长，隔开的涡流区的影响被抵消。 - By comparing the dry plate pressures drop and distributions of velocities simulated on single valve with those of double valves , it was found that there was intense turbulence in the flow fields around fixed - valve , there were eddy areas between valve side orifices and tray wall , there were eddies above the valves too , these led to the complex behaviors of gas perforating valve , these had a great effect on the gas - liquid mass transfer process . at the same time , in order to prevent the disadvantageous effect of gas between one valve with another on the gas - liquid mass transfer , it was very effective to change the fields of gas perforating valve by folding the edges of valve
通过对数值模拟得出的单阀和双阀塔板的干板压降及流场速度分布分析对比后发现，固定阀周围流场存在较强的湍动，阀侧孔与塔板壁面区域以及阀体的上方空间存在明显的涡流区，使气体穿阀后的行为变得复杂，并对气液传质过程产生重大影响；模拟结果表明，为防止和削弱固定阀间的对冲造成的“死区”对传质带来的不利影响，通过折边来改变气体的气路是非常有效的，模拟值与实验值基本得到吻合。 - For shelters , the results show : 1 ) to reduce the raining drops entering into the inlet and to decrease the influence of the vortex , the declining angle of 45 is recommended for the shelters ; 2 ) it is better to choose those shelters which are longer 100 mm ~ 200 mm than the height of the inlets , as they may protect the room from rain
对于单侧百叶风口的挡雨板，计算表明: 1 )为了防止雨水随空气流入自然进风口，并且使风口尽量少受涡流区的影响，建议选用倾斜角度为45 “的挡雨板; 2 )建议选用长度比风口高度长100mm - - 200 “的挡雨板，可以较好的避免挡雨板过短将雨水带入室内和过长影响风口进风的情况。
