In this short course, we have gone a long way toward understanding of modeling of microstructured suspensions, abeit only in a limited regime of suspensions, the dilute concentration limit. Rigorous results can be obtained at higher concentrations, but at the polydispersed regime. But all that is just “the first step” in a “thousand li journey”, Lao Tzu (Fig. 6.1). We wrap up this Lecture Note with some perspectives on microstructured suspension modeling.
