Abstract
The qualitative and quantitative relationship of numerical simulation to the
physical phenomena being modeled is of paramount importance in compu-
tational physics. If the phenomena are dominated by irregular (i.e., nonsmooth or
disordered) behavior, then pointwise comparisons cannot be made and statistical
measures are required. The problem we consider is the gas curtain Richtmyer-
Meshkov (RM) instability experiments of Rightley et al. [13], which exhibit
complicated, disordered motion. We examine four spectral analysis methods for
quantifying the experimental data and computed results: Fourier analysis, struc-
ture functions, fractal analysis, and continuous wavelet transforms. We investigate
the applicability of these methods
