Dynamical hysteresis in the dissipation in turbulent flows
M. Ahmad, P. D. Mininni, M. Obligado +1
We present evidence of the dynamical hysteretic nature of dissipation in unsteady turbulent flows. Wind tunnel experiments and direct numerical simulations in oscillating flows sho…
Interaction of two high Reynolds number axisymmetric turbulent wakes
M. Obligado, S. Klein, J. C. Vassilicos
The interaction between turbulent axisymmetric wakes plays an important role in many industrial applications, notably in the modelling of wind farms. While the non-equilibrium high…
The non-equilibrium part of the inertial range in decaying homogeneous turbulence
M. Obligado, J. C. Vassilicos
We use two related non-stationarity functions as measures of the degree of scale-by-scale non-equilibrium in homogeneous isotropic turbulence. The values of these functions indicat…
Length scales and eddy viscosities in turbulent free shear flows
Gioacchino Cafiero, Martin Obligado, J. Christos Vassilicos
In the present paper, we address the important point of the proportionality between the longitudinal integral lengthscale () and the characteristic mean flow width () using e…
