提出了溶液中开放囊泡的流体动力学模型来研究生物脂质膜中孔的扩大和收缩。囊泡由扩散界面建模。引入了允许对孔隙和孔隙边缘进行一致处理的传输方程。通过有限差分法进行的动态模拟显示了拉伸囊泡中孔的演变。模拟结果包括膜形状、水运动和能量耗散的直接可视化。与显微镜实验获得的数据进行比较。
A hydrodynamic model of open vesicles in solution is presented to study the enlarge- ment and shrinkage of a pore in a biological lipid membrane. The vesicle is modeled by diffusive interfaces. Transport equations permitting consistent treatment of the pore and pore rim are intro- duced. Dynamic simulations implemented by the finite difference method show the evolution of a pore in stretched vesicles. Simulation results include direct visualization of the membrane shape, water motion, and dissipation of energy. Comparison is made with data obtained from microscopy experiments.
