PREFACE
Computational aeroacoustics is rapidly emerging as an essential
element in the study of aerodynamic sound. As with all emerging
technologies, it is paramount that we assess the various opportuni
ties and establish achievable goals for this new technology. Essential
to this process is the identification and prioritization of fundamental
aeroacoustics problems which are amenable to direct numerical siIn
ulation. Questions, ranging from the role numerical methods play in
the classical theoretical approaches to aeroacoustics, to the correct
specification of well-posed numerical problems, need to be answered.
These issues provided the impetus for the Workshop on Computa
tional Aeroacoustics sponsored by ICASE and the Acoustics Division
of NASA LaRC on April 6-9, 1992. The participants of the Work
shop were leading aeroacousticians, computational fluid dynamicists
and applied mathematicians. The Workshop started with the open
ing remarks by M. Y. Hussaini and the welcome address by Kristin
Hessenius who introduced the keynote speaker, Sir James Lighthill.
The keynote address set the stage for the Workshop. It was both
an authoritative and up-to-date discussion of the state-of-the-art
in aeroacoustics. The presentations at the Workshop were divided
into five sessions - i) Classical Theoretical Approaches (William
Zorumski, Chairman), ii) Mathematical Aspects of Acoustics
(Rodolfo Rosales, Chairman), iii) Validation Methodology (Allan
Pierce, Chairman), iv) Direct Numerical Simulation (Michael
Myers, Chairman), and v) Unsteady Compressible Flow Computa
tional Methods (Douglas Dwoyer, Chairman).
There was also a panel discussion on the last day. The panel was
chaired by Sir James Lighthill and consisted of the chairmen of the
various sessions. The goals of the panel discussion were to delimit
the state-of-the-art in computational aeroacoustics and ascertain the
most fruitful avenues for immediate research effort. A report of these
final discussions by Sir James Lighthill is included in this volume. In
addition, each of the session chairman has included some of their
own views in their papers in this volume.
One significant discussion of the panel concerned whether compu
tational aeroacoustics represented a totally new approach to the field
or merely heralded a "second golden age" of aeroacoustic research.
On the basis of the work presented, it was concluded that the ex
act acoustic analogy approach, perhaps utilizing numerical methods
vi
for source computation, would continue to have a significant role to
play for certain problems and that direct numerical simulations pro
vided additional opportunities that might properly initiate a "second
golden age."
