A necessary and sufficient form of two-point velocity characteristic function to embody two-point velocity distribution in turbulence is constructed on the mathematical basis of homogeneity and isotropy. This is applied in the first equation (for one

The non-dimensional prefactor of the Kolmogorov 2/3 law in the inertial range of homogeneous isotropic turbulence (HIT) has been believed to be a universal constant for many years, and then people ...

It is proved that the famous third-order structure function of the velocity in homogeneous isotropic turbulence derived by Kolmogorov implies the statistical interdependence of the difference and sum of the velocities at two points separated by a dis

A decaying homogeneous isotropic turbulence is treated on the combined bases of the Kolmogorov hypothesis and the cross-independence hypothesis (for a closure of the Monin–Lundgren (ML) hierarchy of many-point velocity distributions) in turbulence.

It has recently been known that local high-gradient regions of an advected scalar, such as temperature or mass contaminant, in a turbulent state of fluid form thin sheets, randomly oriented and moving around with turbulent motion. Here is presented a

The refined similarity hypothesis for isotropic turbulence established by Kolmogorov in 1962 is generalized so that the statistics of similarity variable may have a slight scale-ratio dependence. A reasonable form of the dependence is given on the ba

As is well known, there appear innumerable, randomly posed, unsteady, vorticity-concentrated slender regions, which may be called “worms,” moving around in isotropic turbulence with a high Reynolds number. The universal feature of instantaneous s

The one-dimensional (1D) surrogates of scalar dissipation rate as well as energy dissipation rate are often used in place of the true ones in investigations relevant to the Obukhof-Corrsin spectral form and the joint-multifractal nature of isotropic

Experimental and numerical studies relating to the effects of side-wall temperatures on the flow pattern of Rayleigh-Benard cells in a rectangular enclosure with an aspect ratio of 6:2: 1 (length: width: height) are presented. Experiments were carrie
