| Abstract: | This report presents some new progresses in the numeri-cal simulation of the flow field over real configurations at subsonic, tran-sonic and supersonic flows,including the technique to generate surface and spatial grads,stable and efficient flow field solver,i.e.LU factoriza-tion scheme.The software for engineering purposes has been developed and extensive calculations have been carried out for practical flow fields of fore-fuselages,complete aircrafts and fore-fuselage/inlets.The compu-tation results are compared with experiment data, and the agreement is good.This software is a basis for further development of software for many fluid mechanics problems in many engineering departments. |
