Response of shear stress to ac electric fields under steady shear flow in a droplet-dispersed phase.
We have measured the response of shear stress to ac electric fields under steady shear flow in the droplet-dispersed phase of an immiscible polymer blend. A characteristic mode was found under steady shear flow, the relaxation frequency of which increased with increasing the shear rate. In the frequency dispersion, a scaling relation derived from dimensional analysis was confirmed to hold. The ...
متن کاملNonequilibrium steady-state response of a nematic liquid crystal under simple shear flow and electric fields.
The effect of a dc electric field on the response of a nematic liquid crystal under shear flow has been investigated by measuring the shear stress response to an ac electric field used as a probe. It was found that both the first- and second-order responses do not vanish at high frequencies, but have constant nonzero values. The experimental results are in good agreement with calculations based...
متن کاملBicontinuous Microemulsions under Steady Shear Flow
Dynamic response of microemulsions to shear deformation on the basis of twoorder-parameter time dependent Ginzburg-Landau model is investigated by means of cell dynamical system approach. Time evolution of anisotropic factor and excess shear stress under steady shear flow is studied by changing shear rate and total amount of surfactant. As the surfactant concentration is increased, overshoot pe...
متن کاملThe approach to steady state in microemulsions under shear flow
We present an analitical study of the dynamical process of the approach to steady state for a driven diffusive system represented by the microemulsion phase of a ternary mixture. The external applied field is given by a “plane Couette”shear flow and the problem is studied within the framework of a time-dependent GinzburgLandau model. A Fokker-Planck equation for the probability distribution of ...
متن کاملRich Janus colloid phase behavior under steady shear.
We study the assembly of single-patch colloidal Janus particles under steady shear flow via Brownian dynamics simulations. In the absence of flow, by varying the Janus patch size and the range and strength of the anisotropic interaction potential, Janus colloids form different aggregates such as micelles, wormlike clusters, vesicles and lamellae. Under shear flow we observe rearrangement, defor...
