Abstract
Official abstract text for this publication.
Apparatus features a container and a transducer. The container is made of a selected material and has a container wall with a selected thickness, and configured to hold a fluid therein. The transducer is configured on the outside of the container wall, and is also configured to provide a standing wave into the fluid. The selected thickness and material of the container wall is chosen to ensure about a ½ wavelength of a desired frequency exists within the container wall, so as to substantially reduce back reflections toward the transducer due to any mismatch in acoustic impedance at the interface between the container wall and the fluid, and so as to substantially maximize the amount of energy delivered to the fluid, thus improving the operating efficiency of the apparatus.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus comprising: a container having a container wall characterized by a combination of both, being made of a selected type of material and having a selected thickness, the container being configured to hold a fluid therein; a transducer configured on the outside of the container wall, and also configured to provide a standing wave having a wavelength with a desired frequency into the fluid; the at least one parameter of the container wall being s…
