燃气射流 meaning in English
hot jet
Examples
- Numerical study on gas - solid two - phase jet flow and solid particle erosion
燃气射流气固两相数值模拟与颗粒冲刷分析 - The simulation results were studied the interaction mechanisms among burning jet flow and upstream flow were demonstrated
分析和比较了模拟结果，揭示了空气来流和燃气射流对弹箭的干扰机理。 - 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。
