Acoustic Droplet Ejector
Application ID: 140311
Acoustic droplet ejection is a non-contact, highly controllable method for liquid handling emerging in applications such as printing, biomedical, semiconductor assembly, and mass spectroscopy. The modeling approach assumes separation of acoustic and flow time scales. First, a focused acoustic field is created using Pressure Acoustics, Frequency Domain. Second, the droplet formation is modeled using Two-Phase Flow, Level Set. Effects of both the acoustic radiation pressure at liquid-air interface and the volume force due to acoustic streaming are included using the Acoustic-Streaming Domain Coupling.
