Multiphase Flow

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.

Scaling Yield and Mixing in Chemical Reactors

Scaling chemical reactions from the lab to pilot or production requires a detailed understanding of the physical system, which frequently involves heat transfer, mass transfer, reaction kinetics, and fluid flow. This case study illustrates how multiphysics simulations can support design decisions involved in scaling up chemical reactors.

Tank Sloshing Simulation

During sloshing, liquid exerts a dynamic force on the surrounding vessel, which may cause leakage or damage to the vessel or its supporting structure. We used a mesh-free smoothed particle hydrodynamics (SPH) method to predict liquid sloshing and its effect on the deformation and stresses in a vessel.

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.

Computational Fluid Dynamics (CFD)

Veryst offers state-of-the-art consulting in the design and analysis of gaseous and fluid systems and products. We employ advanced CFD analysis to solve problems involving fluid mixing, multiphase flow, phase change, non-Newtonian fluids, and microfluidic effects.

Fluidic Mixing

Veryst has deep expertise in fluidic mixing processes, which we leverage for our clients across industries.  A fundamental aspect of mixing is the stretching and folding of the interface between initially separated substances.  This occurs in many forms a

Fluid–Structure Interaction

Fluid-structure interaction refers to the analyses involving simultaneous fluid flow and solid deformation.  Veryst Engineering has worked on a wide range of FSI problems of different complexities. 

Microfluidics

Veryst offers a comprehensive approach to solving problems in microfluidic device development.  We employ an array of modeling tools, such as scaling arguments, analytical formulas, computational simulations, and laboratory testing to inform the design and integration of common components.

Webinar on modeling microfluidic devices with COMSOL Multiphysics

Dr. Matthew Hancock co-presented a webinar titled "Modeling Microfluidic Devices with COMSOL Multiphysics," which focused on enhancing modeling and design processes for lab-on-a-chip devices, biosensors, micromixers, inkjet nozzles, and other microfluidic systems.
