中文拼音 [suōfàngpēnguǎn]
縮放噴管
英文
contracting-expanding nozzle-
A convergent - divergent nozzle based burner and its numerical simulation
縮放式噴管燃燒器及其數值模擬Connect the choke and kill lines to slip joint
將放噴和壓井膠管與伸縮節連通。Attach the riser tensioners, choke and kill lines to the slip
將隔水管張力器，壓井及放噴管線連到伸縮節上。Remove the high pressure choke and kill hoses from the slip joint
從伸縮節上卸開高壓放噴和壓軟管。Study on gas - solid two - phase flow in laval nozzle and laval nozzle length
縮放噴管內的氣固兩相流動和縮放噴管長度的研究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。Based on one dimension flow theory and lagrange method, the correlation of speeding rate of particles under gas flow drag with the size of particles and the length of laval nozzle used for the gas and solid two - phase separation test apparatus was studied
摘要採用一元流動理論和拉格朗日方法，研究了用於氣、固兩相分離試驗裝置的縮放噴管內，被氣流拖曳的顆粒加速率與顆粒大小和縮放噴管長度的關系。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。分享友人
