In this paper, some basic CFD problems are studied, including ENO/WENO schemes, CFD systematic analysis, object-oriented programming method and zone divided parallel algorithm. These methods enriched and advanced the CFD algorithms, and then these algorithms were applied in numerical applications of the scarfed reversal nozzle and the open cavity. This promotes the speed of the CFD algorithm combine with the project applications.
