Drag, lift and torque coefficients for ellipsoidal particles

, 2013
In this work, we want to verify the ability of the CFD code Ansys Fluent© to give an accurate prediction of hydrodynamic forces acting on non-spherical (Ellipsoids). We focus the present study only on the drag and lift forces and also on the pitching torque.

Mimicking Life: Autonomous Oscillating Artificial Cilia Driven by Chemical Power

Advanced Intelligent Systems, EarlyView.
The synthesis and motion analysis of chemically actuated, individually autonomous artificial cilia are presented. Driven by an internal chemical reaction, the self‐driven individual cilia require no external stimuli. They undergo periodic oscillatory motion with a 3D beat pattern and exhibit chemotactic shifts, reminiscent of biological systems.
