缸内紊流计算

Calculation of the Turbulend Flow in Cylinder

气缸内气流是以紊流形式存在 ,在计算气缸对流传热时要知道气流的特征速度和特征长度。本文介绍的紊流模型能准确提供特征速度和特征长度参数的数值。

Airflow in cylinder exists in the form of turbulent flow. in order to calculate the convective exchange of cylinder, we have to know the characteristic length and the characteristic velocity of airflow. The paper presents a model of turbulent flow, which can exactly provide data of the characteristic length and velocity of turbulent flow.
