Case Studies

Water electrolysis for hydrogen production is a key enabling technology for global decarbonization. In this case study, Veryst simulated the electrical current distribution and gas generation in a proton exchange membrane electrolyzer stack to identify potential process inefficiencies and recommend optimal operating conditions

The performance of peristaltic pumps is influenced by tube dimensions, tube material, rotary mechanism, and fluid properties. Veryst Engineering developed a strongly coupled fluid-structure interaction model that captures the deformation of the tube, rollers, and fluid, including contact.

The call for structures that can selectively block acoustic waves of certain frequencies is growing, but their design is often inhibited by the lack of appropriate simulation tools in commercial FEA packages. Veryst developed a COMSOL Multiphysics model for unit cell band gap simulations, enabling the design and optimization of phononic band gap structures with target band gap width and locations.

A plastic clip used to retain a patient support failed, resulting in an occupant death. Veryst was asked to determine the cause of failure.

Cold forging often results in the development of high residual stresses that might lead to premature cracking of the cold forged component. Machining, which often follows cold forging, results in the re-distribution of residual stresses. We developed an FE-based strategy capable of predicting the residual stresses in the final machined configuration of cold forged components.

Manufacturing medical diagnostic kits involves drying reagents to be reconstituted later, during use. For this project, Veryst simulated reagent dry-down of a small volume of liquid in a microwell to investigate the effect of process parameters including oven temperature and humidity.

Redox flow batteries offer numerous advantages for long-duration energy storage, including decoupled energy and power, long service life, and safe, scalable design. In this case study, Veryst used multiphysics simulation to evaluate the performance and guide the design of kilowatt-scale flow battery cells for modular storage applications.

Radio frequency tissue ablation is a commonly used and minimally invasive tissue treatment procedure. Accurately modeling this kind of coupled multiphysics problem is often challenging. Veryst developed a COMSOL Multiphysics model accounting for heat transfer, electric field, and fluid flow to study the RF tissue ablation problem where an electrode is targeting a tissue close to a blood vessel.

Understanding the movement and behavior of droplets a person emits by breathing is essential for infectious disease control. Veryst modeled the trajectory of particles from an individual running at a moderate pace with another runner in their slipstream, while both are exhaling without wearing a mask.
