摘要
流体壁面剪应力的标定是实现该类传感器测量的前提。本文介绍了目前主要的3种壁面剪应力静态标定方法和2种动态标定方法,研究了剪应力基准发生原理、标定装置组成及适用范围。归纳总结了各类标定方法的优势与缺点,为壁面剪应力传感器标定方法的合理选择提供参考。
Wall shear stress measurement with micro sensors is an effective means to study the flow friction. It is fundamental and important work to calibrate the sensors accurately. Three static and two dynamic calibration methods are introduced in this paper. The calibration devices, working principles, and behavioral models of wall shear stress measurement are analyzed. The features of calibration methods are summarized, and advice is provided for selecting the proper calibration method.
