二维血管收缩的分子动力学建模

Modeling Of Blood Vessel Constriction In 2-D Case Using Molecular Dynamics Method

Mohamad Rendi, Suprijadi, Sparisoma Viridi

摘要:

血管收缩的模拟与粒子为基础的方法,使用分子动力学创作软件称为分子动力学(WM)。血流和血管壁,在构建血管时考虑的唯一组件,都以粒子形式表示,具有相互作用势:Lennard-Jones势,推拉弹簧势和弯曲弹簧势。介质或血浆的影响通过斯托克斯阻力调节在血浆粘度中。已经观察到,压力p随着收缩部c的增加而增加。血管的泄漏开始于80%的收缩,这表明存在血管壁可以克服的最大压力。

英文摘要:

Blood vessel constriction is simulated with particle-based method using a molecular dynamics authoring software known as Molecular Workbench (WM). Blood flow and vessel wall, the only components considered in constructing a blood vessel, are all represented in particle form with interaction potentials: Lennard-Jones potential, push-pull spring potential, and bending spring potential. Influence of medium or blood plasma is accommodated in plasma viscosity through Stokes drag force. It has been observed that pressure p is increased as constriction c is increased. Leakage of blood vessel starts at 80 % constriction, which shows existence of maximum pressure that can be overcome by vessel wall.
