Numerical Wind Tunnel (NWT) and CFD research at National Aerospace Laboratory

The National Aerospace Laboratory (NAL) of Japan is the only national research institute for aerospace engineering and services in Japan. NAL is a pioneer of supercomputer development and utilization in Japan. Since 1993, NAL has developed the Numerical Wind Tunnel (NWT), consisting of 166 parallel-connected Fujitsu vector processors and has been providing substantial computational power resources to scientists and industries since 1993. This paper describes the background of NWT's development, its present status and computational fluid dynamics (CFD) research being carried out on NWT.
