Conference paper


The interaction between a low-density spot and a compression shock in non-ideal fluids is studied using the linear interaction theory. Unlike in ideal fluids, the spot can be made to generate powerful sound or extreme shear rates. This is a general property of any substance featuring a local minimum in its sound speed. The selectivity of the refracted field may offer novel strategies to enhance mixing or for sound mitigation in high-speed flows.
