Velocity and Energy Profiles In Two- vs. Three-Dimensional Channels: Effects of Inverse vs. Direct Energy Cascade
Victor S. L'vov, Itamar Procaccia, Oleksii Rudenko
In light of some recent experiments on quasi two-dimensional (2D) turbulent channel flow we provide here a model of the ideal case, for the sake of comparison. The ideal 2D channel…
Turbulent Fluxes in Stably Stratified Boundary Layers
Victor S. L'vov, Itamar Procaccia, Oleksii Rudenko
We present an extended version of an invited talk given on the International Conference "Turbulent Mixing and Beyond". The dynamical and statistical description of stably stratifie…
Drag Reduction in Homogeneous Turbulence by Scale-Dependent Effective Viscosity
Roberto Benzi, Emily S. C. Ching, Itamar Procaccia
The phenomenon of drag reduction by polymer additives had been studied in simulations on the basis of non-Newtonian fluid mechanical models that take into account the field of poly…
Shell Model for Drag Reduction with Polymer Additive in Homogeneous Turbulence
Roberto Benzi, Elisabetta De Angelis, Rama Govindarajan +1
Recent direct numerical simulations of the FENE-P model of non-Newtonian hydrodynamics revealed that the phenomenon of drag reduction by polymer additives exists (albeit in reduced…
