| Abstract: |
| In this presentation, we will introduce a thermodynamically consistent phase field model for multi-component vesicles in fluids. Our model encompasses dual two-phase fluid systems: one to depict the interaction dynamics between the vesicle and its ambient fluid, and the other to capture the dynamics of the multi-component on the vesicle membrane. These two systems are coupled within a diffuse domain framework, which provides a high-accuracy approach for solving partial differential equations on complex surfaces. We will illustrate a series of numerical examples showcasing classical scenarios encountered in multicomponent vesicles, including phase separation, tank treading, and phase treading. Additionally, we will validate the accuracy of our model by comparing these simulations with experimental observations. |
