Progress and future prospects of CFD in aerospace-Wind tunnel and beyond

To find out revolutionary effort, the message given by Prof. Dean Chapman in 1977 is referred. Observation of current CFD research reveals that evaluation methods of “scale effect” that were believed to be the most important benefit of CFD have not yet been established. Such establishment is the key for the revolution of CFD and researchers need to focus their effort on the development of technologies to evaluate scale effect. Only with such new CFD technologies can “conceptual design with CFD” become feasible.
