ABSTRACT:The properties of the interstellar medium strongly suggest that it is turbulent, in the generalized sense of nonlinear systems which exhibit
unpredictable temporal behavior accompanied by self-organizing spatial
fluctuations covering a wide range of size scales.
This paper reviews a number of
theoretical approaches to the problem.
These include phenomenological models
designed to explain the observed scaling relations and virialization
constraints, direct numerical solutions of the hydrodynamical equations,
applications of statistical turbulence closure methods, and solutions of local
model equations which suggest limit cycle and chaotic behavior.
