Flow curves on dense suspensions exhibit highly nonlinear behaviors consisting of shear thinning, shear thickening, and multiple Newtonian regions. Moreover, it has recently been revealed that each Newtonian viscosity diverges individually with increasing density and is respectively related to the glass and jamming transitions. In this review, recent advances in physics are introduced regarding the complex flow behaviors in dense suspensions and its relation to the glass and jamming transitions. In addition, a numerical simulation model, focusing mainly on discontinuous shear thickening, is presented to provide microscopic insight into the complex flow behaviors, i.e., the role of thermal fluctuations and interparticle forces acting on the particles. Finally, a perspective on discontinuous shear thickening is presented with reviewing recent experimental and theoretical (numerical) works.
