Acoustics & Sensors Technology Team

The AST team develops tools for noninvasive fluid identification and characterization that include physical property determination including fluid flow. It also develops novel techniques that use various forces (ultrasonic, electric, magnetic, etc.) to control movement of fluid phases in mixtures, emulsions, etc. These forces are used to separate fluid/gas/solid phases. Underpinning many of the AST team’s inventions is acoustic resonance and understanding the nature of resonance in various systems.  While resonance at low power is used for fluid diagnostic purposes, resonance at higher power is used for fluid and particle movement. One of the main techniques used by this team is the swept frequency acoustic interferometry (SFAI) and its various adaptations for studying fluids, emulsions and suspensions. In addition, this team also develops tools that employ nonlinear acoustics for imaging and material characterization.  A combination of ultrasonic techniques (SFAI, nonlinear acoustics, Doppler Spectroscopy, etc.) is used to visualize fluid flow and suspended microscopic particles. The team focuses on developing novel tools for solving problems for the industry and the government.

Team Members: Dipen Sinha (Team Leader), Cristian Pantea, Curtis Osterhoudt, John Brady, Farid Mitri, Anirban Chaudhuri, and Blake Sturtevant.
