Springer New Developments in Computational Fluid Dynamics: Proceedings of the Sixth International Nobeyama Workshop on the New Century of Computational Fluid ... Mechanics and Multidisciplinary Design, 90)

It is a joyful and ?tting moment that we, the friends, colleagues and suppo- ers of Prof. Kunio Kuwahara, dedicate this Workshop to Prof. Kuwahara. We gathered in late April of 2003 in the tranquility of Nobeyama mountain resorttocommemoratethe60thbirthdayofProf.Kuwaharawhichhadfallen in November, 2002.

Looking back on the occasion of Kan-re-ki (the 60th birthday), a man is supposed to have accomplished something of meaningfulness and value. With these undertones, it will be a useful exerciseto recount the spl- did accomplishments of Prof. Kuwahara. The major professional achievements of Prof. Kuwahara may be c- pressed into two main categories. First and foremost, Prof. Kuwahara will long be recorded as the front-line pioneer in using numerical computations to tackle complex problems in ?uid mechanics. His unquenching zeal in com- tation and utilization of computers is unmatched throughout the globe. His infatuation with the Supercomputers of 1980's and 1990's is now a legend in the ?uid dynamics communities. He continues to stand tall on the leading edge of computational ?uid mechanics research and industrial applications. In short, Prof. Kuwahara has ?lled in a chapter in the history of modern ?uid dynamics research.
