| الوصف: | We introduce and investigate nu-merically a thermodynamically consistent simple model of a drop or vesicle in which the interfa-cial surface contains multiple constitutive compo-nents (e.g. amphiphilic molecules). The model describes the nonlinear coupling among the flow, drop/vesicle morphology and the evolution of the surface phases. We consider a highly simplified version of the Helfrich model for fluid-like vesi-cle membranes in which we neglect the effects of bending forces and spontaneous curvature but keep the effects of inhomogeneous surface ten-sion forces. Thus, this model may also describe liquid drops. To solve the highly nonlinear, cou-pled system a new numerical method is devel-oped. This method combines the immersed inter-face method to solve the flow equations, and the Laplace-Young jump conditions, with the level-set method to represent and evolve the interface and a non-stiff Eulerian algorithm to update the mass concentration on the drop interface. Re-sults are presented for drops/vesicles in an applied shear flow where an initially unstable mixture of the surface mass separates into distinct phases. 1 |
