overlapping wave
1.The overlapping grid technique and symmetric TVD scheme are used to simulate the flow field of lateral jet interaction for two missile configurations. The vortex and wave structures of this flow field are shown and the topology of separation flow is given according to the computational results. The interaction effects on aerodynamic characteristic are studied.
2.In fact, the deep overlapping of the wavepacket of particles implies new interactions which are technically called nonlinear (in the sense of depending on powers of the wavefunctions bigger than one), nonlocal (in the sense that they are extended over the volume of wave-overlappings which cannot be evidently reduced to finite number of isolated points), as well as nonpotential (in the sense of being of contact / zero{range type for which the notion of action-at-a-distance potential has no mathematical or physical meaning of any type}.
