Problems solved by technology
Removal of planar standing waves may prevent continuous operation
Also, the amount of power used to create a standing acoustic plane wave tends to heat the primary fluid through waste energy, which can be detrimental to the material being processed
[0006] Thus, conventional acoustophoresis devices have limited efficacy due to several factors, including heat generation, use of planar standing waves, restricted fluid flow, and inability to trap different types of materials
[0007] Control of the power supplied to the ultrasound transducer is challenging to implement, especially for efficient performance

Embodiment
[0164] A 2D numerical model was developed for the acoustophoresis device using the COMSOL simulation software. The model is in Figure 13 shown in . The device comprises an aluminum wall 222 and a stainless steel reflector 224 opposite the wall. Embedded in the wall is a piezoelectric transducer 230 . As shown, the transducer is in the form of a 4-element piezoelectric array. Wall 222 and reflector 224 define a flow chamber, and arrow 225 indicates the direction of fluid flow through the flow chamber. The piezoelectric transducer is in direct contact with the fluid. Channels / cutouts 210 and potting material 212 are also shown, although no potting material was used in the simulation.
[0165] The simulation software was run and its output compared with published data (Barmatz, J. Acoust. Soc. Am. 77, 928, 1985). Figure 14A The acoustic potential U is compared. Figure 14B The x-component of the acoustic radiation force (ARF) is compared. Figure 14C Compare the y compo...

Abstract
Aspects of the disclosure are directed to an apparatus for separating a second fluid or a particulate from a host fluid. That apparatus comprises a flow chamber with at least one inlet and at least one outlet. A drive circuit configured to provide a drive signal to a filter circuit configured to receive the drive signal and provide a translated drive signal. An ultrasonic transducer is cooperatively arranged with the flow chamber, and transducer includes at least one piezoelectric element configured to be driven by the current drive signal to create an acoustic standing wave in the flow chamber. At least one reflector opposing the ultrasonic transducer to reflect acoustic energy.
