摘要
利用热线风速法,研究了汽油机缸内紊流运动的变化规律,介绍了平均气流速度、紊流强度、紊流尺度、能量谱密度等随曲轴转角的变化过程,还介绍了紊流尺度和能量谱密度的近似计算方法。
In this paper, the change regularity of turbulence characteristics in cylinder of gasoline engines is studied. The change processes of mean velocity, turbulence intensity, turbulence scale, energy spectral density atc. is introduced. The approximative calculating method of turbulence scale and energy spectral intensity is introduced.
