摘要

为研究目前常用的楔形、圆盘形两种冲击波测压装置对所测冲击波的影响,运用仿真软件Fluent,建立测压装置外流场的二维有限元模型,模拟稳态平面流场中不同压强下两种测压装置表面及其附近流场区域的压强变化规律。壁面压力测试结果表明:两种测压装置的传感器安装方式都应选择装置的上表面,楔形测压装置比圆盘形测压装置对所测激波的影响小。

Abstract

In order to study the influence of the commonly used wedge or disc shape of shock wave pressure measuring device on the measured wave, the simulation software Fluent was used to study the influence. A two-dimensional finite element model for flow field of pressure measuring device was established. The change rule of surface pressure of measuring device and the flow field area pressure near it under different pressure of steady planar flow field was simulated. Wall pressure test results show that sensor installation method of both pressure measuring device should be chosen on the surface of the device. The wedge shape of pressure measuring device has less influence on the measured shock wave than the disc shape device does.

Key words： shock wave; flow around; numerical simulation; pressure measuring device
