EXPERIMENTAL EVALUATION OF FLOW ATTRIBUTE INSIDE THE CIRCULATED FLOW GENERATION APPLIED FOR ANGULAR RATE SENSOR

Abstract

In this paper, the author presents experimental analysis of a miniature device that can generate multiple circulated jet flows. The device is actuated by a lead zirconate titanate (PZT) diaphragm. The flows in the device were studied using three-dimensional transient numerical simulation with the programmable open source OpenFOAM and was comparable to the experimental result. Each flow is verified by two hotwires mounted at two positions inside each consisting chamber. The experiment confirmed that the flow was successfully created through transient characteristic of flow analysis. Moreover, the capability of the device in measuring angular rate is also experimental test. The device is robust, is minimal in size, and can contribute to the development of multi-axis fluidic inertial sensors.
