COMSOL Multiphysics is a powerful tool in theoretical study. Lei Zhou, Jiping Huang and other professors in Physics Department, Fudan University have achieved some exciting results of soft, tunable metamaterials. We use it to study non-equilibrium behavior of rhoeological (ER) fluids and polar molecule dominated rheological (PM-ER) fluids. Numerical solutions using the Onsager’s principle would yield a two-phase continuum model which can predict realistic behaviors of ER fluid dynamics. After solving such PDEs in COMSOL, we find lamellar structures of ER fluids under electric field and shear flow. The simulation results are compared to the experiment, and they could answer to each other.
