Abstract

The gravitational settling of a flexible, permeable circular and planktonic particle drenched in a fluid which is assumed to be Newtonian and incompressible along with being viscous was studied. A mathematical formulation and numerical simulations of the studied problem were done by applying the Immersed Boundary Method (IBM) in a two-dimensional fluid domain. Parametric studies were done for analyzing the impact of varying flexibilities and permeabilities with reference to settling velocity (terminal velocity) and shape deformation of the particle. The terminal velocity and permeability of the particle are directly proportional. It was observed that for fixed permeability, the terminal velocity increases when increasing the flexibility of the particle.

应用浸没边界法研究柔性、可渗透圆形浮游颗粒的重力沉降
研究了一个具有弹性、可渗透的圆形浮游粒子在粘性牛顿不可压缩流体中的重力沉降问题。利用浸入边界法在二维流体域中建立了问题的数学表达式并进行了数值模拟。根据沉降速度(终端速度)和颗粒的形状变形,进行了参数化研究,分析了不同柔韧性和渗透率对颗粒的影响。粒子的终端速度与渗透率成正比。观察到,在渗透率固定的情况下,随着颗粒柔韧性的增加,终端速度也随之增加。
