| 摘 要： | 描述了一种利用激光、PSD(position sensitive detector)元件及计算机数据采集系统测量湍流场气体密度及其脉动统计平均值的方法;并在流场是轴对称统计定常的假设条件下,建立了测量数据处理的数学模型。用这种测量技术可以定量地获得湍流场内部的统计平均特性。

| Abstract: | This paper describes a measurement method of statistical mean of the gas density and its fluctuation intensity in the turbulent field using a system composed of laser and PSD element and computer data collector.A mathematical model for experiment data processing was found based on an assuming that the flow field was axial symmetric and statistically stationary.And the quantity statistical mean characteristic inside the turbulent field can be obtained by using this technique described by this paper. |
