fuel stream meaning in English
燃料流
Examples
- While the speed is very large , the fuel - air mixing behind the airstream is decreased and the span that the fuel flow in the second combustor is reduced , so the combustion efficiency is decreased , h ) if the fuel streams impinge with the airstreams directly at the air - inlet exit , it make against increasing the combustion efficiency , i ) increasing air - to - fuel ratio within proper range can increase the combustion efficiency
增加燃气喷射速度有利于增强回流区强度，头部燃烧温度上升，但速度太大则会减弱燃气同空气在进气道下游的掺混燃烧，减少燃气在室内停留时间，燃烧效率降低； 8燃气射流与空气流在进气道出口直接撞击不利于燃烧效率的提高； 9在适当范围内增大空燃比能显著提高燃烧效率。 - The mixing of air and fuel can be improved , d ) adding air distributary valve at exit of air - intake can increase the amount of air bifurcated into the dome region , so the value of combustion efficiency is increased , e ) increasing gas generator nozzle number can improve combustion characteristics in the dome region and produce good condition for combustion progress , f ) when the fuel streams are ejected into the second combustor with a angle , the combustion efficiency is increased , g ) when the speed of fuel streams increased , the intension and temperature of recirculation region is improved
两个进气道在补燃室周向成180度布置，有利于增强燃气同空气的掺混； 4在进气道出口增加空气分流挡板，有利于增加进入头部的空气流量，提高燃烧效率； 5增加燃气喷管数量能增强燃气同空气在头部的燃烧效果，为燃烧的进行创造良好的条件； 6
