通用襟翼喷射飞机模型的漩涡分析
The wake behind a simpli¯ ed model of a generic aircraft (the SWIM model) is measuredin the Low Speed Low turbulence wind tunnel (LSL) at Delft University of Technology.Two measurement techniques have been used in order to qualitatively and quantitativelymeasure the wake, i.e. stereoscopic particle image velocimetry (Stereo PIV) and a 5 holeprobe (5HP). Furthermore balance measurements have been carried out over a range ofcon¯ gurations for later comparison purposes. The goal of the wake measurements is togive a comparison between the two measurement techniques.The 5HP measurements are processed using a windows based program called PressureField Visualisation. This program calculates vector ¯ elds from the input pressure dataand has several exporting options. The Stereo PIV measurements are correlated usingDaVis 7.3 using a window size of 16 x 16 pixels with 50% overlap.
