Case Studies

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.

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.

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.

The design of compression springs is tied to their intended function and the acceptable levels of deformation and stress that the spring can withstand. Veryst designed and evaluated a standalone simulation application to capture important qualities, such as spring rate, natural frequencies, and estimated fatigue life, for both helical and conical compression springs.

Arrays of impinging fluid jets are an effective design solution for applications requiring large heat transfer rates. This case study demonstrates the ability of computational fluid dynamics (CFD) to predict heat transfer coefficient distributions and guide design choices to improve cooling uniformity.

Some of the most sensational goals in soccer history came from free-kicks and long shots. (Remember Roberto Carlos’ famous 1998 free-kick?) Veryst investigated the effect of friction between ball and boot, the ball’s internal pressure, and ball materials on the ball’s rotational velocity to understand ball/boot interaction.

How does a soft fluidic gripper perform when inflated and how does it interact with its environment? This is a challenging, yet essential, question to the design and integration of soft robotics in the industry. Veryst Engineering developed a finite deformation Abaqus model to study the behavior, performance, and stability of soft fluidic grippers, providing insight to the design and assessment of soft robots and devices.

Veryst can predict the ultimate strength and failure modes of design concepts generated using topology optimization and produced using additive manufacturing. We use advanced finite element analysis (FEA) that accounts for the nonlinear behavior of the material being used to make the part.

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.
