Latest Patents

Patrick's latest patents include innovative designs for vibration-based acoustic flowmeters. These flowmeters are specifically designed for use in inaccessible nuclear reactor spaces. One of his patents describes a system where a vibration detector identifies vibrations caused by a standing wave. This technology allows for the calculation of fluid flow rates based on the length of the passage and the known properties of the fluid. Additionally, his work on pipe-organ-type flowmeters features a passage with a constricted opening followed by a widening section. This design creates turbulence that generates a standing wave and vibration, facilitating accurate flow rate measurements.

Another patent focuses on acoustic flowmeters and methods of using them. This invention includes an extension that obstructs fluid flow and a detector that captures vibrations from vortex shedding in the fluid. The frequency of these vibrations is crucial for determining the flow rate. By utilizing the Strouhal number, the flow speed can be calculated based on the extension's surface diameter and the detected vortex shedding frequency. Patrick's designs allow for multiple flowmeters with customized physical properties to be used together, enhancing their versatility and application.
