We investigate the influence of hydrodynamic and particle-particle interactions on the microstructure and rheological properties of semidilute colloidal suspensions of structureless particles. The time evolution is described in a mesoscopic setting in which the correlation tensor ssecond moment of the pair correlation functiond is used as the microstructural state variable. Numerical solutions of the governing equations are then presented as linear and nonlinear responses of the suspensions to simple viscometric flows.
