吊钟形涡流室内涡流及气体温度分布的研究

Investigation of Swirl Motion and Temperature Spatial Distribution of Air Charge in Cylindrical Swirl Chamber

用热线风速仪测量了拖动工况下涡流室式柴油机吊钟形涡流室内的气流平均速度和气体温度，研究了涡流室内气流切向速度和气体温度的空间分布及随其曲轴转角变化的规律。

The instantaneous velocity and the temperature of the air charge in the cylindrical swirl chamber of a motored IDI diesel engine are measured by hot wire anemometers. The digital data collecting and processing of the experimental results is performed on a computer by statistical methods. The spatial distributions and the temporal variations of the tangential velocity component and temperature of the air charge in the swirl chamber are investigated.
