喷嘴出口 meaning in English
jet exit
nozzle exit
nozzle inlet
Examples
- Greater temperature gradient and higher thermal stress were the main reason that caused the failure of the exit surface of the cws ceramic nozzle
根据对陶瓷水煤浆喷嘴磨损形貌、温度分布和热应力的分析，得出陶瓷水煤浆喷嘴出口处较大的温度梯度和热应力是导致其出现破损和脱落的主要原因。 - The effect of the height between nozzles and ground plate , the distance between the nozzles , the inlet velocity of the nozzles , and the velocity of the cross flow on the flowfield structure were studied one by one
分别就喷嘴距地面高度、喷嘴间距、喷嘴出口速度、横向流等，对喷射垂直撞击平板流场的影响，逐一讨论。 - The influences of the inlet tube angle , backpressure and driving jet velocity on static pressure distribution in the gas - solid injector are calculated , and the effects of the inlet tube angle on particle bulk phase concentration and axial mean speed of particles in the gas - solid injector are analyzed firstly . the predicament caused by lack of measuring means on the particle velocity in experiments is solved
分析了收缩角、背压和气体喷嘴出口速度对气固喷射器内静压分布的影响，以及收缩角对气固喷射器内固体颗粒体积浓度场和颗粒平均速度的影响，解决了喷射器内固体颗粒速度试验测试手段缺乏的困境。 - A reasonable position of driving nozzle helps to achieve the maximum material flow that also depends on other parameters such as backpressure , properties of conveyed material and driving gas . it is observed that , an increase of convergent section angle is harmful to the pneumatic conveying system , and also influences on the mass flow rate of conveyed material , the distribution of static pressures in injector and the pressure drops of conveying pipe . in addition , within a reasonable scope of air mass rate , increasing the driving jet velocity is more advantageous than enlarging the dimension of driving nozzle
试验研究发现，气体喷嘴位置对气固喷射器的输送能力影响最大，气体喷嘴存在某一最佳位置，而这一最佳位置与背压、输送物料特性和输送风特性相关联；气固喷射器的收缩角对其输送能力、内部静压分布和输送管阻力特性均有适量影响，收缩角增大对整个输送系统均不利；在适当的输送风范围内，提高气体喷嘴出口速度比扩大气体喷嘴尺寸更为有利，但气体喷嘴出口速度过高会增加气固喷射器和输送管内的能量损耗，给输送带来不利的影响；系统背压与气固喷射器的气体喷嘴出口速度的选取有关。 - It was found that the ultra - fine powder can flow smoothly in a spouted bed with a draft tube under some sorts of design parameter and operating condition , thus a new effective method to improve fluidization quality of the ultra - fine powders is obtained ; at higher supplied gas velocity , an increase in the solid circulation rate is observed ; the extent of the distance between the nozzle and the draft tube inlet result in the promotion of the solid circulation rate ; the solid circulation rate increase with increasing the draft tube diameter or the bed mass ; the gas bypassing is nearly zero in the present work ; and the solid flow in the annulus is observed as a moving bed
结果表明：在一定的床层结构和操作条件下，超细粉可以在导向管喷动床中实现平稳流化，从而为改善超细粉的流化质量提供了一种有效的新方法；固体循环速率与喷动气流量、导向管直径、导向管底部与喷嘴出口间距以及床层装填量成正比；气体则基本上不存在“旁路”现象；环隙区中的颗粒流动表现为一移动床特征。
