| الوصف: | We investigate colloidal suspensions under shear flow through numerical experiments. By measuring the time-correlation function of a bond-orientational order parameter, we find a divergent time scale near a transition point from a disordered fluid phase to an ordered fluid phase, where the order is characterized by a nonzero value of the bond-orientational order parameter. We also present a phase diagram in the $(\rho, \dot{\gamma}^{\mathrm{ex}})$ plane, where $\rho$ is the density of the colloidal particles and $\dot{\gamma}^{\mathrm{ex}}$ is the shear rate of the solvent. The transition line in the phase diagram terminates at the equilibrium transition point, while a critical region near the transition line vanishes continuously as $\dot{\gamma}^{\mathrm{ex}} \rightarrow 0$.
