Pirozzoli and Grasso  studied the influence of initial compressibility on flow topology in compressible isotropic turbulence and found that the p.
That is, in the flame zone with negative dilatation (P > 0), a fluid element tends towards stability and the stable topology probability increases gradually, while, in the flame zone with positive dilatation (P < 0), a fluid element tends towards instability and the unstable topology dominates, in accordance with the conclusions of Suman and Girimaji  on compressible isotropic turbulence and Wang and Lu  on compressible turbulent boundary layers.
Measured turbulence levels during this work is less than 9%, which Bruun (1995) showed that the problem of rectification is limited below the level considering homogeneous and isotropic turbulence
v'w'] are defined by various pressure-rate-of-strain models of the isotropic turbulence
written in terms of variation of constants [C.
RSM provides anisotropic turbulence to flows; when the hypothesis of turbulent viscosity is used, the model gives isotropic turbulence
The closure assumptions of the k-[epsilon] model are only valid for high-intensity and nearly isotropic turbulence
Chapters cover the motion of particles and heat exchange in homogeneous isotropic turbulence
and gradient turbulent flows; collisions of particles in a turbulent flow; and dispersion, collision, and clustering of monodispersed and bidispersed particles in homogeneous turbulence.
Most eddy viscosity models assume isotropic turbulence
structures, which could fail for flows with strong anisotropic behaviors, such as swirling flows and flows with strong curvatures.
Above T = 1 K, with viscosity present, it has been shown that grid turbulence is equivalent to homogeneous isotropic turbulence
in a classical fluid.
Measured turbulence levels during this work were less than 35%, which Bruun (1995) showed that the problem of rectification is small below this limit, considering homogeneous and isotropic turbulence
Particle response and turbulence modification in isotropic turbulence
Pierre et Marie Curie) and Cambon (mechanics, French National Center for Scientific Research) draw upon their significant research in their examples, and consider the needs of the practitioner in their organization, starting with an explanation of the statistical analysis of homogeneous turbulent flows and moving on to incompressible homogeneous isotropic turbulence
, including pure rotation (anisotropic) strain, pure shear, buoyancy and stable stratification.
