This video is an animation of turbulent mixing between two gases that occurs following the interaction of a shock wave with the interface that initially separates the gases. The different colours represent different concentration levels of the heavier gas. The animation was generated from a numerical simulation performed on a supercomputer that required over 1 million CPU hours to complete. Understanding how the two gases behave in this idealised scenario is crucial for understanding more complex fluid flows that occur in nature such as supernovae, as well as in practical applications like high-speed combustion and inertial confinement fusion.
