Abstract

Scale-Adaptive Simulations of store release fromweapon bays using overset grids are presented in this paper. A six-degree-of-freedommodel is coupled with the HMB3 flow solver, and store release simulations are performed for a finned store inside an idealised bay. A wavelets analysis revealed that the tonal noise radiated from the cavity is generated by standing waves. It is also found that the trajectories of stores released from the cavities are affected by the mean flow field, the standing waves, and the dynamics of the shear layer formed along the cavity opening.
