Mixing in modulated turbulence. Analytical results
Wouter Bos, Robert Rubinstein
Recent numerical results show that if a scalar is mixed by periodically forced turbulence, the average mixing rate is directly affected for forcing frequencies small compared to th…
Dissipation in unsteady turbulence
Wouter Bos, Robert Rubinstein
Recent experiments and simulations have shown that unsteady turbulent flows, before reaching a dynamic equilibrium state, display a universal behaviour. We show that the observed u…
Mixing in modulated turbulence. Numerical results
Yuyao Yang, Robert Chahine, Robert Rubinstein +1
Direct numerical simulations are carried out to investigate scalar mixing in an isotropic turbulent flow with a time-periodic forcing. For high amplitudes of the modulation, it is…
Depletion of nonlinearity in two-dimensional turbulence
Andrey Pushkarev, Wouter Bos
The strength of the nonlinearity is measured in decaying two-dimensional turbulence, by comparing its value to that found in a Gaussian field. It is shown how the nonlinearity drop…
Reduction of mean-square advection in turbulent passive scalar mixing
Wouter J. T. Bos, Robert Rubinstein, Le Fang
Direct numerical simulation data show that the variance of the coupling term in passive scalar advection by a random velocity field is smaller than it would be if the velocity and…
Reynolds number effect on the velocity increment skewness in isotropic turbulence
Wouter J. T. Bos, Laurent Chevillard, Julian F. Scott +1
Second and third order longitudinal structure functions and wavenumber spectra of isotropic turbulence are computed using the EDQNM model and compared to results of the multifracta…
On the unsteady behavior of turbulence models
Robert Rubinstein, Wouter J. T. Bos
Periodically forced turbulence is used as a test case to evaluate the predictions of two-equation and multiple-scale turbulence models in unsteady flows. The limitations of the two…
