Shear Wave Speed - REU Supplement

本研究旨在开发一种仪器来测量液体中脉冲产生的横波的速度。所提出的装置由同心圆柱体组成，圆柱体之间有充满流体的间隙。外筒进行脉冲旋转，通过监测内筒的运动来检测横波的传递时间。这种仪器对探测液体的分子结构应该是有用的。本文提出的工作是建立在先前开发的仪器的基础上，从许多方面对该仪器进行升级，例如改进轴承等。仪器研制完成后，将在资金许可的情况下对若干液体进行测试。

This research seeks to develop an instrument to measure the speed of impulsively generated shear waves in liquids. The proposed device consists of concentric cylinders with a fluid-filled gap between them. The outer cylinder is rotated impulsively, and the transit time of the shear wave is detected by monitoring the motion of the inner cylinder. This instrument should be useful for probing the molecular structure of liquids. The work proposed here builds on a previously developed instrument, upgrading that instrument in many ways, such as improved bearings, etc. Upon completion of instrument development, it will be tested, as funding permits, on a number of fluids.
