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.
Calrod Thermal Analysis
How fast does a Calrod heat up and how high are the stresses during heating? To answer these questions Veryst Engineering developed a coupled electric-thermal-structural multiphysics model of the Calrod, accounting for conduction, convection, and radiation.
Design and Simulation of a Catheter-Based Acoustic Ablation Device
Thermal ablation is a minimally invasive way to treat tumors, and simulating the physics of ablation can help in the design of ablation devices. Veryst designed and simulated a catheter-based acoustic ablation device relying on acoustic pressure waves to heat tissue to induce necrosis.
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.
Infant Incubator Thermal Modeling
The main environmental factor affecting a premature neonate is thermo-neutrality, as the baby is incapable of regulating and maintaining his/her body temperature at a constant level. Veryst developed a computational model of heat transfer inside an infant incubator to optimize its design.
Laminar Static Mixer Analysis
Laminar static mixers are often employed in industrial environments when the mixing of two or more fluids is required. However, their performance is impossible to analyze with a pure CFD approach. Veryst, in collaboration with Nordson EFD, developed a unique computational modeling tool to evaluate and optimize the design of such mixers.
LED Light Bulb Heat Transfer Simulation
Both the efficiency and life of an LED bulb drop when operated at high temperature. Given the wide range of possible shapes and sizes of heat sinks, Veryst Engineering developed a rapid and effective tool to compare design alternatives and estimate LED temperatures.
Microfluidic Mixer Concentration Profile
Veryst developed a coupled CFD mass transfer model to predict a microfluidic mixer configuration appropriate for mixing pure and salt water channels.
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.
Phononic Band Gap Analysis
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.
RF Tissue Ablation Simulation
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.
Sea Floor Energy Harvesting
Veryst Engineering developed proof-of-concept models for a device for harvesting energy from constant low speed ocean floor currents in order to power ocean sensors.
