本文在气道稳流模拟试验基础上,对有关气道性能及影响性能的几项参数进行了分析。介绍一种定量求螺旋气道的“螺旋气流涡流比”、“切向气流涡流比”和“总涡流比”以及定性分析切向气流分布的方法,同时还介绍一种应用稳流模拟试验数据计算进气终了时缸内的涡流比和充气效率的方法。
Based on the simulation of airway steady flow, several parameters related to airway performance and performance are analyzed in this paper. This paper introduces a method of quantitatively determining the “helical flow vortex ratio”, the “tangential flow vortex ratio” and the “total vortex ratio” of spiral airways and the qualitative analysis of tangential gas flow distribution. At the same time, a method of applying steady flow simulation test data The method of calculating the vortex ratio and the charging efficiency in the cylinder at the end of the intake air.
