Abstract: |
The viscous nonequilibrium swirling flows in a divergent duct are simulated by solvingN-S equations, and the enhancement techniques of mixing and combustion in supersonic flows areinvestigated. The results show that the swirling of fuel is an effective enhancement method forsupersonic mixing and combustion. |
