Tumbling and tank-treading dynamics of individual ring polymers in shear flow

摘要: The dynamics of individual ring polymers in a shear flow is studied by hybrid mesoscale simulation approach. New insight into the provided: exhibit both tumbling and tank-treading motions. A novel angle autocorrelation function proposed to analyze motion that usually coexists with may be applied other highly deformable soft objects such as vesicles. dependence average gyration tensor, orientation angle, frequencies determined quantitatively. simulations also reveal existence apparently increases intrinsic viscosity under flow.
