Mesoscopic lattice Boltzmann modeling of soft-glassy materials

A multi-component lattice Boltzmann model with short-range repulsion between different species and short/mid-ranged attractive/repulsive interactions between like-molecules is introduced.
The interplay between these composite interactions is found to be capabe of describing a rich configurational dynamics of the density field, which can describe many features of soft-glassy materials, such as long-time relaxation due to caging effects, anomalous enhanced viscosity and aging effects under shear.
