Acoustically Triggered Harvesting of Nanometer Airborne Particles – A Numerical Model for the Ultrasonic Manipulation

Acoustically Triggered Harvesting of Nanometer Airborne Particles – A Numerical Model for the Ultrasonic Manipulation

In this study, the focus is to model the physics of acoustic harvesting for 100 nanometer particles in order to lay the groundwork for technical feasibility studies. Based on a simplified 2D test-case channel geometry with an intense acoustic standing wave field the relevant drag and acoustic forces...
