Abstract: | The characteristic of a supersonic inlet system with three-dimensional bump which is substituted for the diverter or conventional
ramp-type compression systems has been studied numerically. A comprehensive numerical analysis has been performed to understand
the threedimensional flow field including shock/boundary layer interaction and growth of turbulent boundary layer that might
occur around a three-dimensional bump in a supersonic inlet. The current numerical simulations showed the supersonic bump-type
inlet which is modified from a conventional ramp-type inlet to control shock/boundary layer interaction effectively and evolved
to maximize inlet performance. |
