High-Speed Stereo PIV System for Advanced Flow Control Diagnostics in Offset Diffusers

Abstract

It is proposed to acquire a high-speed, high-resolution stereo particle image velocimetry (SPIV)system comprised of two high speed CMOS cameras (6,242 fps at 1,200 ~ 800 pixels to 20,978 fpsat 512 ~ 512 pixels) and a high repetition rate (up to 10 kHz) dual-head diode-pumped Nd:YLFlaser (30 mJ/pulse @ 527 nm). This SPIV system will significantly extend the diagnosticcapabilities in a current ONR research program (N00014-14-1-0014) at Georgia Tech(experimental) and Boeing (numerical) that focuses on advanced active flow control (AFC)approaches for mitigation of flow distortion and losses in aggressive supersonic inlet diffusers ofcompact aircraft engines.
