流截面 meaning in English
flow area
Examples
- Study of loss of flow section on the border of sudden shrink and sudden expansions in pipeline
相邻过流截面突然缩小与扩大阻力相互影响的研究 - With the different tripping annulus at the inlet , a new method of the distance definition from the wall was used to measure 35 mean velocity profiles on seven sections in the pipe length x / d = 125 . 2
采用新的离壁距离标定方法，在入口处设有改变扰动强度挡环的条件下，利用热线仪在管长x d约为125的范围内完成了七个不同管流截面上的35个轴线方向速度分布的测量工作。 - The paper deduced the relations between the phase fractions of the multiphase flow and measured signals , such as the dielectric constant from the capacitance sensor , the electrical conductivity from the conductance sensor , and the ratio of absorption from the rf sensor
推导了多相流的介电常数、电导率、吸收率和含率的关系，设计和制作了电容、电导、射频传感器以及处理电路，提出了基于这些技术的多相流截面含率的测量方法。 - In this way , when obturation cubage leave absorb oil cavity it connects the eduction oil cavity with the v trough and with the increasing of the turning angle , the size of the cross section of v trough become bigger and bigger , which make the pressure between the cavity of two blades much higher and higher , and until it completely connects the eduction oil cavity , it reaches the pressure of the eduction , and it can effectively reduces the fluid noise caused by high pressure return flow
这样，当密闭容积离开吸油窗口之后，通过v型尖槽逐渐与排油窗口连通，随着转角的增加， v型尖槽通流截面积逐渐增大，这就使两叶片间容腔内的压力逐渐升高，直至完全接通排油窗口时，才升压达到压油腔的压力，这样可以有效地降低因高压回流而引起的流体噪声。 - At the same time , when the gas flow passes the flow area of the inlet valve at a high speed , turbulent throw - outs will appear and lead to the generation of high frequency noises . as the flow area of the inlet valve keeps changing , the turbulent noise is of fixed frequency range ( generally over 1 000 hz )
与此同时，当气流以高速流经进气门流通截面时，产生湍流脱体，导致高频噪声的产生，由于进气门通流截面是不断变化的，因此湍流噪声具有一定的频率范围，主要集中在1000hz以上的高频范围。
