Spectral energy transfer in a viscoelastic homogeneous isotropic turbulence

The Physics of Fluids, 2019
Energy dynamics in elastoinertial turbulence is investigated by performing different direct numerical simulations of stationary, homogeneous isotropic turbulence for the range of Weissenberg numbers 0 ≤ Wi ≤ 9.

Deterministic forcing of homogeneous, isotropic turbulence

Physics of Fluids, 1994
A deterministic low-wave-number forcing scheme designed to obtain statistically stationary homogeneous, isotropic turbulence in incompressible flows, and address criticisms of earlier schemes is proposed. Three-dimensional turbulent kinetic energy spectra collapse well and are more consistent with the experimentally determined Kolmogorov coefficient ...

Bubbles in Isotropic Homogeneous Turbulence

2012
An experimental study of the bubble deformation in an isotropic homogeneous turbulent flow field was carried out. It is of a fundamental importance to understand the rate of coalescence and breakup in two phase disperse flows.

Homogeneous Isotropic Turbulence

1977
Many theoretical investigations of turbulence have been developed around the concept of homogeneous, isotropic turbulence — turbulence of which the statistical properties do not vary with position and have no preferred direction. An approximation to such a motion can be obtained behind a grid, such as the one shown in Fig. 21.1, in a wind-tunnel.

Homogeneous isotropic turbulence: large momentum expansion

Physica A: Statistical Mechanics and its Applications, 1999
High temperature expansion is an effective tool for studying second order phase transitions. With this in mind, we have looked at a high momentum expansion for homogeneous isotropic turbulence. Combining our results with those of the inertial range, we give another view of extended self-similarity (ESS).

Lattice Boltzmann simulations of decaying homogeneous isotropic turbulence

Physical Review E, 2005
Decaying homogeneous isotropic turbulence in inertial and rotating reference frames is investigated to evaluate the capability of the lattice Boltzmann method in turbulence. In the inertial frame case, the decay exponents of kinetic energy and dissipation and the low wave-number scaling of the spectrum are studied.

A theory of homogeneous isotropic turbulence

Applied Scientific Research, 1959
Homogeneous and isotropic turbulence has been discussed in the present paper. An attempt has been made to find the simplifying hypothesis for connecting the higher order correlation tensor with the lower ones. Starting from the Navier-Stokes equations of motion for an incompressible fluid and following the usual method of taking the averages, a ...

Particle-Turbulence Interaction in a Homogeneous, Isotropic Turbulent Suspension

Applied Mechanics Reviews, 2006
A review is given of numerical, analytical, and experimental research regarding the two-way coupling effect between particles and fluid turbulence in a homogeneous, isotropic turbulent suspension. The emphasis of this review is on the effect of the suspended particles on the spectrum of the carrier fluid, in order to explain the physical mechanisms ...
