This paper aims to obtain more insight in the physics of cavitudyudflows. CFD results are analysed using a superposition of refleudctedudacoustic waves driven by the cavity flow showing clearly the rudelativeudamplitude, and the time modulation of cavity tones. The tonaudl, anduda part of the broadband noise, is found to be driven by the turbudu-udlent length scales, disabling the phase superposition of thude smallerudwavelength. This can be seen as a way to complement the estab-udlished Rossiter formula. In addition Scale-Adaptive Simuludations ofudstore release from weapon bays using overset grids are preseudnted. Audsix-degree-of-freedom model is coupled with the HMB3 flow soudlver,udand store release simulations are performed for a finned storude insideudan idealised bay. It is found that the trajectories of storesudreleasedudfrom the cavities are affected by the mean flow field, the standinudgudwaves, and the dynamics of the shear layer formed along the caudvityudopening.
