进气道性能 meaning in English
inlet characteristic
Examples
- The existence of angle of attack reduces the inlet performance
攻角的存在也在一定程度上降低了进气道性能。 - An experimental study on intake - ports characteristics of a four - valve diesel engine
四气门柴油机进气道性能的试验研究 - On basis of the modeling results , the effects of mach number , attack angle and ramp angle on the inlet performance are analyzed
根据此数学模型，分析了攻角和进口气流马赫数对进气道性能的影响，同时给出了斜板对进气道性能的影响。 - Other content in this paper is the design and investigation of spiral inlet port . the geometries that compose intake port have been repeatedly when intake port scheme was designed . the intake port scheme has been carried out steady - flow test . the experiment data has been analyzed and investigated , then the performance of inlet port has been estimated by the fluid coefficient and the whirl ratio . at last , the spiral inlet port scheme has been selected based on matching relation of the factors of combustion system . in addition , how to " intake port synthesis performance coefficienf ' evaluate engine intake port has been discussed
本文的另一项内容是螺旋进气道的设计和研究。通过对进气道的几个主要结构参数进行反复修改拟定进气道方案，并对其进行稳流试验，分析和研究试验数据，利用流通系数、涡流比进行进气道性能评估，根据燃烧系统要素的匹配关系，确定了两种螺旋进气道方案。另外，本文探讨了“进气道综合性能系数”对发动机涡流进气道性能的评估能力。
