laval velocity 中文意思是什麼
-
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
?了更好地實現氣、固兩相分離，顆粒在縮放噴管出口處的速度應該足夠大，因而縮放噴管就應該足夠長。 -
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
提出了用增加縮放噴管長度的方法，使含塵高溫高壓氣體中的灰塵顆粒獲得實現氣固兩相分離所必需的更高動量的途逕。 -
It is shown that with the decrease in size of particles, their velocity at the exit of laval nozzle increases under the conditions of both the invariable gas parameters and the same laval nozzle length ; the laval nozzle length increases with the size of particles under the same speeding rate of particles
研究表明，在氣流參數和縮放噴管長度不變的情況下，被氣流拖曳的顆粒越大，顆粒在縮放噴管出口處的速度就越低；在顆粒加速率相同的情況下，顆粒越大，所需的噴管長度就越長。
