Claim:
1. A method for separating a second fluid or a particulate from a host fluid, comprising: flowing a mixture of the host fluid and the second fluid or particulate through an acoustophoretic device, the acoustophoretic device comprising: sending a voltage signal to drive the at least one ultrasonic transducer in a displacement profile that is a superposition of a combination of different modes that are the same order of magnitude to create the multi-dimensional acoustic standing wave in the acoustic chamber such that the second fluid or particulate is continuously trapped in the standing wave, and then agglomerates, aggregates, clumps, or coalesces together, and subsequently rises or settles out of the host fluid due to buoyancy or gravity forces, and exits the acoustic chamber.
