Computational Fluid Dynamics (CFD)

Laminar Static Mixers
Velocity and streamlines in a static mixer

Veryst possesses advanced computational fluid dynamics (CFD) capabilities.  We solve hard-to-address problems often involving coupled and nonlinear behaviors, such as those found in fluid/solid interaction, fluid/thermal coupling, multiphase flow (droplets, colloidal flows, phase change), and species transport and reactions.  Our work frequently employs multiphysics CFD tools to model mixing and transport in chemical reactors, including design optimization at pilot and production scales.  We have also modeled air flow and heat transfer through a device to optimize electronic cooling. 

Our clients use our analysis and recommendations to develop new products and systems, and to improve the performance of existing products and systems, which in some cases has resulted in new intellectual property.
