Case Studies

Many engineering applications require understanding the behavior of polymers under cryogenic temperature conditions. Veryst developed a test fixture and method to test materials submerged in liquid nitrogen (LN2) at its boiling temperature of -196°C.

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.

Thermal management is crucially important for battery performance in consumer products, electric vehicles, and grid-level storage systems. In this case study, Veryst used multiphysics simulations to evaluate different thermal management strategies in prismatic and cylindrical battery packs.

Veryst developed a diffusion model accounting for the different layers of the human skin in order to predict the drug concentration profile of a transdermal drug delivery process.

Permeation enhancers are used to improve drug delivery through the skin by altering the structure and dynamics of the skin. Veryst developed a finite element model of drug diffusion from an adhesive patch that accounts for the effect of permeation enhancers.

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.

When would an automotive disc brake need to be replaced? The continuous frictional sliding between two deformable surfaces leads to wear accumulation and ultimately failure of the weakest component. However, wear modeling is not readily available in most finite element codes. Veryst developed a wear model in COMSOL Multiphysics using differential equations for the wear depth based on a modified version of Archard's law.
