Temperature fluctuations induced by turbulent dissipation

Temperature fluctuations induced by turbulent dissipation

In practically every fluid flow, kinetic energy is converted into heat through viscous friction. In a turbulent flow this heat is generated in an inhomogeneous way and the temperature (...)

Axisymmetric turbulence

Axisymmetric turbulence

Recently, theoretical progress has been made on the statistical mechanics of axisymmetric turbulence. The predictions include the formation of large-scale structures. Results in agreement with (...)

Non-equilibrium turbulence

Non-equilibrium turbulence

In a wide range of turbulent flows, the distribution of energy between scales is well-described by the Kolmogorov-Richardson cascade phenomenology. But when such an equibrium-cascade is (...)

Depletion of nonlinearity

Depletion of nonlinearity

It is often mistakenly assumed that statistical approaches such as the Direct Interaction Approximation or EDQNM cannot predict anything on structure related issues since all phase-information is (...)

Lagrangian Statistics

Lagrangian Statistics

In the Lagrangian description, i.e., following individual fluid particles, the complexity of turbulence manifests itself in the curvature and tortuosity of the fluid particle trajectories. We (...)
