In this video for the Gallery of Fluid Motion we use a confocal schlieren system to visualize shock waves produced by an actuator through a trumpet bell. This allows us to model the profile of such a wave as it travels after emission. After they exit from the trumpet, we make them interact with various objects. We were able to observe reflection, transmission, attenuation, diffraction and wave-wave interaction.
