We present results on the connection between the vorticity equation and the shape and evolution of the single-point vorticity probability density function. The statistical framework for theseâ€¦ (More)

We investigate the single-point probability density function of the velocity in threedimensional stationary and decaying homogeneous isotropic turbulence. To this end, we apply the statisticalâ€¦ (More)

It was shown by Oberlack and Rosteck [Discr. Cont. Dyn. Sys. S, 3, 451 2010] that the infinite set of multipoint correlation (MPC) equations of turbulence admits a considerable extended set of Lieâ€¦ (More)

We derive the energy spectrum in wave-number-frequency space for turbulent flows based on Kraichnan's idealized random sweeping hypothesis with additional mean flow, which yields the instantaneousâ€¦ (More)

Natural and artificial networks, from the cerebral cortex to large-scale power grids, face the challenge of converting noisy inputs into robust signals. The input fluctuations often exhibit complexâ€¦ (More)

Rayleighâ€“BÃ©nard (RB) convection in the turbulent regime is studied using statistical methods. Exact evolution equations for the probability density function of temperature and velocity are derivedâ€¦ (More)

Cellular suspensions such as dense bacterial flows exhibit a turbulence-like phase under certain conditions. We study this phenomenon of "active turbulence" statistically by using numerical tools.â€¦ (More)

An analytical model for the streamwise velocity space-time correlations in turbulent flows is derived and applied to the special case of velocity fluctuations in large wind farms. The model is basedâ€¦ (More)
