Examples
- Study on gas - solid two - phase flow in laval nozzle and laval nozzle length
缩放喷管内的气固两相流动和缩放喷管长度的研究 - In order to separate gas and solid two phases completely , the velocity of particles at the exit of laval nozzle should be high enough , therefore the laval nozzle should be long enough
?了更好地实现气、固两相分离，颗粒在缩放喷管出口处的速度应该足够大，因而缩放喷管就应该足够长。 - By increasing the length of laval nozzle , an approach was presented to obtain higher particle velocity necessary for gas - solid separation in dusty gas of high temperature and high pressure
提出了用增加缩放喷管长度的方法，使含尘高温高压气体中的灰尘颗粒获得实现气固两相分离所必需的更高动量的途迳。 - The flow field of fadw is very complicated , especially in the free vortex jet zone . so the method is according to the ideal flow , including the design of the asymmetric supersonic laval nozzle and the diffuser
所以，本文所建立的fadw的基本设计方法是理想状态下的设计方法，其中主要包括非对称超音速喷管的设计和气动窗口扩压器的设计方法。 - The conveying parameters were relatively optimized by adjusting the throat area of adjustable laval nozzle and pressure parameters , so that the foodstuff particle breaking rate during pneumatic conveying was decreased at certain extent
通过调节可调式拉法管的喉径以及各压力参数实现了输送参数的相对最优，在一定程度上减轻了粮食颗粒在输送过程中的破碎率。
