激光诊断速度测量分子示踪速度超音速喷流 laser diagnosis velocity measurement hydroxyl tagging velocimetry supersonic flow

摘要

介绍了研制的小型脉冲高温超音速流场模拟装置。利用OH分子示踪速度测量技术,对实验室建立的小型脉冲高温超音速流场模拟装置产生的喷流速度分布进行了诊断。通过改变测量对应于喷流的空间位置光路调节,改变193 nm激光线相对于喷流的空间位置,分别得到了喷流不同区域的OH分子示踪速度图像,根据图像计算了测量位置喷流沿轴线方向的速度分量的分布情况。结果显示:喷流在压缩区的速度比在膨胀区低得多;在压缩初期区域喷流中心部分速度明显高于两侧部分,而在二次膨胀区域喷流中心部分速度低于两侧部分。

Abstract

A miniature high-temperature supersonic flow simulation device has been introduced.The velocity distribution of the flow produced by the device was diagnosed using hydroxyl tagging velocimetry(HTV).Through changing the spatial position of the 193 nm laser relative to the flow,some HTV experimental images were acquired at different areas of the flow.And axial velocity distributions of the flow were calculated from the images.The measurement results indicated that the velocity of the flow in the compression area is much slower than that in the expansion area.In the initial part of the compression area the velocity at the flow center is higher than that at both sides,while in the second expansion area the velocity at the center is slower.
