• ABSTRACT
• PROGRESS AND FUTURE PROSPECTS OF CFD IN AEROSPACE
• WIND TUNNEL AND BEYOND
• A historical perspective of Computational Fluid
  Dynamics (CFD) in aerospace in last 30 years is
  firstly given. It is shown that there still
  remain a number of problems that are
  geometrically simple but difficult to simulate
  even after many simulations were conducted over
  complex body configurations. The fact indicates
  that CFD research is now in the specific phase
  and requires some innovation.
• The innovation includes evolutionary effort and
  revolutionary effort. As an example of
  evolutionary effort, the LES (Large Eddy
  Simulations)/RANS (Reynolds-averaged
  Navier-Stokes simulations) hybrid method and its
  application examples are presented. Comment is
  given that there may be other types of research
  necessary to make CFD a really useful tool for
  design in addition to simply showing CFD
  capability for complex body configurations.
• To illustrate revolutionary effort, reference
  is made to the message by Prof. Dean Chapman in
  1977. 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 to
  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.
• This talk covers Guggenheim lecture at the 24th
  ICAS conference and authors recent studies in
  CFD.
