Effect of viscoelasiticity on the far-dissipation range of homogeneous isotropic turbulence

The comparison of the results of direct numerical simulations of isotropic turbulence of Newtonian and viscoelastic fluid, based on the FENE-P model, provide evidence that viscoelasticity modifies qualitatively the behavior of the smallest scales: we observe a k⁻⁶ law in the far dissipation range of the energy spectrum and we show...
