Theory and Modelling of Isotropic Turbulence: From Incompressible through Increasingly Compressible Flows [PDF]
AtmosphereHomogeneous isotropic turbulence (HIT) has been a useful theoretical concept for more than fifty years of theory, modelling, and calculations. Some exact results are revisited in incompressible HIT, with special emphasis on the 4/5 Kolmogorov law.

Burgers' Turbulence Models [PDF]
The Physics of Fluids, 1969 A detailed investigation of the stability of the solutions and the growth of secondary solutions beyond the critical points is carried out for the Burgers' model equations. It is found that the transitions at some critical points are very much like the intuitive description given by Landau; however, the possibility of finite jumps is also encountered.

Astrophysical turbulence modeling [PDF]
Reports on Progress in Physics, 2011 The role of turbulence in various astrophysical settings is reviewed. Among the differences to laboratory and atmospheric turbulence we highlight the ubiquitous presence of magnetic fields that are generally produced and maintained by dynamo action.
