Abstract

Abstract:

To quantify the structures of high-speed flow over a cavity, small circle points with equal space in the row and column are used as background for background oriented schlieren (BOS), and image processing techniques of mark points in videogrammetry measurement (VM) are also employed to break the limits of cross-correlation in existing BOS. The expressions for computing refraction angle and displacement of nonparallel beams are derived. The fields of optical path difference (OPD) and refraction displacement when the beams from the small circle points to the center of the camera is crossing the flow are accurately calculated based on VM collinear equations. The measuring data on flow over the cavities in FL-21 wind tunnel demonstrates that the OPD differences no more than 1 μm and refraction angle about 1 μrad can be perceived distinctly, and the structures of waves/vortices/shear layer are quantified. The method proposed can provide a new way to measure aero-optic effects and visualize the complex flows. With simple optical system and no expensive coherent sources, the method has great application potential.

Key words: aero-optics, videogrammetry measurement, flow visualization, schlieren, wind tunnel test, imaging measurement
