Query: Is the Scaling of Supersonic Turbulence Universal?   The statistical properties of turbulence are considered to be universal at
sufficiently small length scales, i. e., independent of boundary conditions and
large-scale forces acting on the fluid. Analyzing data from numerical
simulations of supersonic turbulent flow driven by external forcing, we
demonstrate that this is not generally true for the two-point velocity
statistics of compressible turbulence. However, a reformulation of the refined
similarity hypothesis in terms of the mass-weighted velocity rho^(1/3)v yields
scaling laws that are almost insensitive to the forcing. The results imply that
the most intermittent dissipative structures are shocks closely following the
scaling of Burgers turbulence.
