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…
