inclined overhead valve

The effects of duct inclining angle and gas valve deflection on the characteristic of flow field were analyzed with several laws established.

为提高具有螺旋进气道的内燃机进气通流能力,利用三维、可压、粘性、湍流流动模型,采用任意拉格朗日一欧拉(ALE)计算方法,对其流场进行了研究,并分析了气道倾斜角、气阀偏置等进气系统参数对流场特性的影响。

The effects of the duct inclining angle and position on the characteristic of flow field were analyzed.

为了提高具有螺旋进气道的内燃机的进气通流能力,利用三维、可压、粘性、湍流流动模型,采用求解压力耦合方程的半隐算法(SIMPLE),对其流场进行了研究,并分析了气道倾斜角、气道位置等进气系统参数对流场特性的影响。
