Aerosol Particle Separation
The photo above contains measurements of the driving frequency,
sound pressure, and velocity, and illustrates the particle alignment with
pressure nodes in the acoustic standing wave.
The photos and video clips below further illustrate the
the acoustic force on the aerosol particles in a moving gas stream.
