DESCRIPTION
A direct simulation strategy for predicting supersonic jet noise is
dveloped in this theses. Direct simulations are quickly becoming the
method of choice due to their generality and ever-decreasing expense
associated with the development of parallel processors. The sources
of supersonic jet noise are known to be dominated by the
growth and decay of large scale turbulent structures. The direct
simulation approach used here consists of solving the full Navier Stokes
equations using high-order-finite-difference techniques to simulate the evolution
of these structures and the noise they radiate to the acoustic newar field.
This near field solution is then extrapolated to the far field using
a Kirchhoff method. For additional information,

We're still experimenting with the data. Some interesting products so far
are a QuickTime animation and a sample
sound file that was generated from a numerically sampled point on the
Kirchhoff surface.
