摘要: Spinodal decomposition and nucleation of critical fluids are discussed in the presence laminar shear turbulence on basis recent experiments. In such situations we can realize stationary emulsion-like domain structures due to dynamical balance between thermodynamic instability shear-induced deformations. spinodal case, unique is strong regime which exceeds average relaxation rate order parameter. case enhance aggregation droplets, thus speeding up growth. But if a relatively small value, even droplets be broken, then leading complete suppression droplet formation. We also predict considerable increase effective viscosity large non-Newtonian effect domains course decomposition.
