Title: Compilation of underexpanded impinging jet instabilities

Description: A compilation of 2 axial and 3 helical instability modes of oscillation imaged at 1,000,000 frames per second with a shadowgraphy technique showing which instability modes dominate at different Nozzle Pressure Ratios (NPR) and different impingement distances (H). Note that the high-definition video is available on YouTube on the channel: adamrisborg
