Phys. Rev. Lett. 102, 026002 (2009) [4 pages]Mesoscopic Lattice Boltzmann Modeling of Flowing Soft SystemsReceived 8 August 2008; published 16 January 2009 A mesoscopic multicomponent lattice Boltzmann model with short-range repulsion between different species and short (midranged) attractive (repulsive) interactions between like molecules is introduced. The interplay between these composite interactions gives rise to a rich configurational dynamics of the density field, exhibiting many features of disordered liquid dispersions (microemulsions) and soft-glassy materials, such as long-time relaxation due to caging effects, anomalous enhanced viscosity, aging effects under moderate shear and flow above a critical shear rate. © 2009 The American Physical Society URL:
