CFD (Computational Fluid Dynamics)

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.
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.
Insufflation Analysis
To compare the performance of two gas humidification devices, Veryst Engineering performed gas flow testing, device examination and CFD analysis.
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.
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.
Tank Sloshing Simulation
During sloshing, the 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.
Theoretical and numerical analysis of low-voltage cascade electroosmotic pumps
Electroosmotic (EO) pumps are driven purely by electric fields and have no moving parts. Cascading EO pumps reduces voltage requirements. Veryst used computational fluid dynamics (CFD) and semi-analytical equivalent circuit theory to analyze the complex behavior of these pumps.
