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.
Capillary filling, the autonomous wicking of liquids through hydrophilic microchannels driven by surface tension and wettability, enables pump-free, precise fluid handling in microfluidic devices for the biotechnology, MedTech, semiconductor, and chemical processing fields. In this case study, we present advanced simulations of capillary filling and its dependence on wettability, quantified by the contact angle. Such simulations inform product and process design decisions to enhance efficiency, reliability, and scalability.
High performance liquid chromatography (HPLC) is a high pressure liquid based analytical technique used to separate, identify, and precisely quantify components in complex chemical or biological mixtures, especially in pharmaceutical, clinical, food, environmental, and forensic testing. Particle size distributions can impact HPLC performance, including column efficiency and pressure drop. In this case study, Veryst developed a multi-scale simulation of flow, dispersion, and adsorption within a chromatographic bed, accounting for particle size dispersity and intraparticle diffusion.
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
Inkjet printing, the precise deposition of micro-scale droplets onto solid substrates driven by controlled ejection and surface wetting, enables high-resolution feature formation for printed electronics, functional coatings, and diagnostic device manufacturing. In this case study, we present advanced simulations of inkjet droplet impact and spreading and their dependence on substrate wettability. Such simulations inform substrate selection and process design decisions to improve feature resolution, print reliability, and manufacturing efficiency.
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.
Cavitation, the formation and collapse of vapor bubbles in a liquid due to local pressure drops, can limit performance and reliability in medical devices, energy systems, and process equipment—causing unwanted wear, vibration, and efficiency loss. In this case study, we applied high-fidelity multiphase computational fluid dynamics simulations to capture the unsteady dynamics of cavitation in confined geometries and demonstrate how simulation can guide the development of safer, more efficient, and longer-lasting products and systems.
The physics of droplet formation during dripping, jetting, and atomization governs the accuracy and consistency of a wide array of fluid dispensing and spray technologies. In this case study, we apply high-fidelity multiphase flow simulations to capture the full droplet formation cycle and reveal mechanisms that control necking, breakup, and satellite drop formation. The results demonstrate how simulation can guide the design of more precise, efficient, and reliable fluid dispensing and spray technologies.
Vial filling—the precise transfer of liquids into vials under controlled conditions—is a common process step in pharmaceutical, diagnostic, and laboratory applications, where product quality and regulatory compliance demand exceptional consistency and reliability. This case study compares two filling strategies using moving and fixed inlet nozzles, demonstrating how controlling the distance between the nozzle and the liquid surface can produce clean fills or, conversely, lead to undesirable outcomes such as dripping, splashing, and air entrainment. These results provide practical guidance for engineers seeking to refine filling protocols, minimize waste, and ensure consistently reliable production.

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.
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.
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.
