Case study

Bubble Entrapment in Microchannels
Bubbles trapped in microchannels can distort the fluid flow and impact the device performance. Veryst developed a multiphase CFD model to predict the effect of geometry and surface properties on the likelihood of bubble entrapment.
CFD Modeling for Ventilation System of a Hospital Room
Efficient ventilation can contribute to reducing the energy consumption of buildings and minimize the risk of airborne infection in hospital rooms. Veryst used computational fluid dynamics (CFD) to simulate ventilation in a hospital room as well as the dispersion of particles and droplets.
Immersed Beam Vibration
When a thin structure is immersed in a fluid, its natural frequencies, mode shapes, and damping characteristics may be significantly affected by the fluid. Predicting the dynamic behavior in this case requires a structural-acoustic analysis.
Multiphysics Analysis of a MEMS Switch
The responses of a MEMS switch immersed in fluids differs from that in a vacuum. Veryst Engineering developed a coupled electrostatic-fluid-structure interaction model to investigate the switch response time, deformation, and energy dissipation.
Peristaltic Pump Fluid - Structure Interaction
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.
Underfill Adhesive Flow and Cure
The microelectronics packaging industry relies heavily on adhesive bonding to assemble electronic components. Veryst built a COMSOL Multiphysics model of a thermocompression bonding process to help reduce bonding cycle time by simultaneously optimizing material and process variables.

Service

Acoustics
Veryst has strong acoustic simulation expertise in a wide variety of applications, including medical devices and wearable technology. In many cases, acoustic problems cannot be solved adequately using a single-physics approach, and Veryst has extensive experience in solving multiphysics problems involving acoustics.
Adhesive Joints & Interfaces
Veryst assists clients with the selection of adhesive materials, development of bonding processes, and mechanical analysis of interfaces. We employ chemical characterization, mechanical testing, and advanced computational methods to design robust adhesively bonded structures and to understand delamination failures.
Chemical Reactors & Bioreactors
Chemical reactors and bioreactors involve many layers of physics, including fluid flow, heat transfer, chemical reactions, and porous media. A deep knowledge of the underlying physical phenomena is essential when scaling up reactors.
