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.

Shear Jamming in Dense Suspensions

Shear thickening and jamming in dense particulate suspensions can lead to undesirable processing inefficiencies and failure modes across a variety of product applications, including inkjet printer nozzles, medical autoinjectors, and porous filtration systems.  In this case study, Veryst simulated the flow of a dense suspension through a syringe needle to evaluate the conditions that lead to shear jamming.

Simulation of Cavitating Flow in Confined Geometries

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.

Simulation of Droplet Formation

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.
