Turbulence modeling both addresses a fundamental problem in
physics, 'the last great unsolved problem of classical physics, '
and has far-reaching importance in the solution of difficult
practical problems from aeronautical engineering to dynamic
meteorology. However, the growth of supercom puter facilities has
recently caused an apparent shift in the focus of tur bulence
research from modeling to direct numerical simulation (DNS) and
large eddy simulation (LES). This shift in emphasis comes at a time
when claims are being made in the world around us that scientific
analysis itself will shortly be transformed or replaced by a more
powerful 'paradigm' based on massive computations and sophisticated
visualization. Although this viewpoint has not lacked ar ticulate
and influential advocates, these claims can at best only be judged
premature. After all, as one computational researcher lamented,
'the com puter only does what I tell it to do, and not what I want
it to do. ' In turbulence research, the initial speculation that
computational meth ods would replace not only model-based
computations but even experimen tal measurements, have not come
close to fulfillment. It is becoming clear that computational
methods and model development are equal partners in turbulence
research: DNS and LES remain valuable tools for suggesting and
validating models, while turbulence models continue to be the
preferred tool for practical computations. We believed that a
symposium which would reaffirm the practical and scientific
importance of turbulence modeling was both necessary and timely."
