Computational Fluid Dynamics (CFD) has made remarkable progress in
the last two decades and is becoming an important, if not
inevitable, analytical tool for both fundamental and practical
fluid dynamics research. The analysis of flow fields is important
in the sense that it improves the researcher's understanding of the
flow features. CFD analysis also indirectly helps the design of new
aircraft and/or spacecraft. However, design methodologies are the
real need for the development of aircraft or spacecraft. They
directly contribute to the design process and can significantly
shorten the design cycle. Although quite a few publications have
been written on this subject, most of the methods proposed were not
used in practice in the past due to an immature research level and
restrictions due to the inadequate computing capabilities. With the
progress of high-speed computers, the time has come for such
methods to be used practically. There is strong evidence of a
growing interest in the development and use of aerodynamic inverse
design and optimization techniques. This is true, not only for
aerospace industries, but also for any industries requiring fluid
dynamic design. This clearly shows the matured engineering need for
optimum aerodynamic shape design methodologies. Therefore, it seems
timely to publish a book in which eminent researchers in this area
can elaborate on their research efforts and discuss it in
conjunction with other efforts.
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

signi?cance. 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.
Supercomputer technologies have evolved rapidly since the first
commercial-based supercomputer, CRAY-1 was introduced in 1976. In
early 1980's three Japanese super computers appeared, and Cray
Research delivered the X-MP series. These machines including the
later-announced CRAY-2 and NEC SX series created one generation of
supercomputers, and the market was spread dramatically. The peak
performance was higher than 1 GFLOPS and the compiler improvement
was remarkable. There appeared many articles and books that
described their architecture and their performance on The late
1980's saw a new generation of supercomputers. several benchmark
problems. Following CRAY Y-MP and Hitachi S-820 delivered in 1988,
NEC announced SX-3 and Fujitsu announced the VP2000 series in 1990.
In addition, Cray Research announced the Y-MP C-90 late in 1991.
The peak performance of these machines reached several to a few
ten's GFLOPS. The hardware characteristics of these machines are
known, but their practical performance has not been well documented
so far. Computational Fluid Dynamics (CFD) is one of the important
research fields that have been progressing with the growth of
supercomputers. Today's fluid dynamic re search cannot be discussed
without supercomputers and since CFD is one of the im portant users
of supercomputers, future development of supercomputers has to take
the requirements of CFD into account. There are many benchmark
reports available today. However, they mostly use so called
kernels. For fluid dynamics researchers, benchmark test on real
fluid dynamic codes are necessary."
