FEA of an Acoustically Levitated Liquid Droplet and Its Use in Material Science at the Advanced Photon Source

Acoustic levitation can be used as a sample holding device to facilitate a containment- and contamination-free environment for x-ray characterization. A stable levitation of liquid droplets can be achieved on the nodes of a standing sound wave via the equilibrium of competing forces of gravity and drag with acoustic radiation. Visual observations indicate that the levitating liquid droplets experience jitter in all three directions. Jittering in a levitating droplet has shown a higher rate of evaporation compared to a stable one. To understand the phenomena involved in the evaporation process of acoustically levitated droplets, finite element analysis simulations were performed using COMSOL Multiphysics®. The simulation results were compared with particle imaging velocimetry (PIV) to validate the modeling effort. The simulation and solvent evaporation rate measurements show that the evaporation rate is higher for solvents with higher vapor pressures, lower viscosities, and a lower compressibility factor. This presentation will cover acoustic levitation, its application at APS, and simulation efforts to understand the physics behind acoustic levitation.

An FEA-multiphysics approach can be used to solve and understand the complex material swelling and shrinking of electrolyte-soft polymers such as hydrogel, peptides, pharmaceutical drugs, etc., due to the change in external stimuli. Also, this talk will briefly discuss the use of FEA multiphysics to understand the physical response of some of the materials in science, engineering, biosensing, and biomedical applications.

Lumped Vibroacoustic Receiver Model COMSOL® Integration: Toward the Optimization of Hearing Aid Design

The speaker will briefly present a vibroacoustic circuit-equivalent model of a miniature hearing instrument loudspeaker, known as a receiver, properly coupled with mechanics and acoustics using the Structural Mechanics and Acoustics modules with COMSOL Multiphysics®. The model is a result from a collaborative initiative in the hearing aid industry to integrate the miniature speaker model into accurate vibroacoustic hearing aid simulations. With accurate models, hearing aid designers can virtually select speakers, refine vibration isolation mounts, and package components to reduce the amount of speaker energy that is fed back to the hearing instrument microphones. The overall goal for the models is to expedite and optimize the lengthy and costly process of designing hearing instruments.
