On the Theory of Isotropic Turbulence
Applied Mechanics Reviews, 1989The theory of isotropic turbulence is investigated. In particular it is established that, for self-similar turbulence, energy transfer occurs in two distinct invariant modes. Implications of this result are discussed. The related decay of turbulence intensity is determined.

Temperature structure functions in isotropic turbulence
Physical Review A, 1991A method of modeling isotropic turbulence with a passive scalar is presented that can derive the high-order temperature structure functions with reasonable asymptotic behavior. As a necessary tool for this purpose, a theory of joint intermittency exponents of the dissipation of turbulent energy and scalar variance is developed, which is led to be ...

Acoustic Radiation from Isotropic Turbulence
The Journal of the Acoustical Society of America, 1958For low Mach number turbulence, Lighthill has given a result which expresses the acoustic radiation of turbulent fluid in terms of a fourth-rank velocity correlation. Through the use of the Navier-Stokes equation this relation can be put in terms of the space-time pressure correlation. For very large Reynolds number turbulence (in the inertial subrange

Isotropic Turbulence and Inertial-Range Structure
The Physics of Fluids, 1966The abridged Lagrangian-History Direct Interaction closure approximation is interpreted physically and used to analyze energy transfer, effective eddy viscosities, and Lagrangian spacetime statistics in stationary and decaying isotropic turbulence. The results are then specialized to the inertial range. Numerical values are predicted for the Kolmogorov

Isotropic Turbulence–Shock Interaction
2008This chapter is devoted to the analysis of the interaction of an initially isotropic turbulence with a normal plane shock wave. Even though this case is very simple from a geometrical viewpoint, it will be seen that it involves most physical mechanisms observed in more complex configurations.

The Decay of Isotropic Temperature Fluctuations in an Isotropic Turbulence
Journal of the Aeronautical Sciences, 1951The approach of von Karman and Howarth (to isotropic turbulence) has been applied to the decay of isotropic temperature fluctuations in a decaying isotropic turbulence, under the restriction that the temperature differences are too small to have any effect on the velocity field.
