摘要

本文研究了一系列剪切敏感液晶(Hallcrest制造)在3马赫以下风洞边界层中的性能。通过对CCD视频记录的数字分析，评估了观察到的颜色的变化，包括色调、饱和度和强度。测量程序包括在以下条件下对晶体行为的评估:(i)在3马赫的湍流边界层，(ii)在2马赫的边界层中大约半模型，以及(iii)在旋转钻机中被机械剪切。结果表明，不同的晶体配方具有不同的特性，不能简单地用晶体混合物的粘度来定义。

The evaluation of shear sensitive liquid crystals at Mach 3

This paper examines the performance of a range of shear sensitive liquid crystals (manufactured by Hallcrest) in wind tunnel boundary layers upto Mach 3. The changes in observed color were assessed, using digital analysis of CCD video recordings, in terms of the hue, saturation and intensity. The measurement program included the assessment of crystal behavior under the following conditions: (i) turbulent boundary layer at Mach 3, (ii) around a half model in a Mach 2 boundary layer, and (iii) whilst being mechanically sheared in a rotational rig. The results show that the various crystal formulations possess different characteristics which cannot be defined simply by the viscosity of the crystal mixture.
