Abstract:
Physical features of a flow structure evolution during supersonic small body (pellet) injec-tion towards the flow from the channel of a spherically blunted cylinder are studied. The diameter of cylinder is 35 times larger than of an injected body. Numerical simulation is made on multilevel Cartesian grids with a local adaptation based on the wavelet analysis. The body motion is accounted with the use of free boundary method. Dynamics of a moving body interaction with the bow shock from cylinder, formation of the reverse flow region between bodies, its evolution and disappearance, and subsequent establishment of a stationary flow are studied. Reduction of a main body drag to the level 0.2 of the initial one is demonstrated.
