| 摘 要： | 为了定量分析湍流中浓度、温度等标量的输运过程,需要同时获取流场空间内速度和标量的脉动值,以确定湍流扩散特征量。详细介绍了同步应用粒子图像测速与平面激光诱导荧光技术开展测量和数据处理的方法,并应用该方法获取了槽道内两种流体的湍流扩散通量等特征量。研究结果表明,该方法可有效地应用于湍流扩散研究领域。

| Abstract: | To do quantitative analysis for the transport process of scalars in turbulence, such as concentration and temperature, it is necessary to acquire the velocity and scalar fluctuations value in flow fields at the same time so that to determine characteristics of turbulent diffusion. The methods of measuring and data processing by application of simultaneous particle image velocimetry (PIV) and plane laser-induced fluorescence (PLIF) techniques are introduced in detail. Moreover, the methods are used to obtain the turbulent mass flux of two fluids in the turbulent channel flow. The results show that the method can be applied effectively in the field of turbulent diffusion. |
