Case study

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.
Sea Floor Energy Harvesting
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.
Tank Sloshing Simulation
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.


Adhesive Joints & Interfaces
Veryst assists clients with the selection of adhesive materials, development of bonding processes, and mechanical analysis of interfaces. We employ chemical characterization, mechanical testing, and advanced computational methods to design robust adhesively bonded structures and to understand delamination failures.
Computational Fluid Dynamics (CFD)
Veryst offers state-of-the-art consulting in the design and analysis of gaseous and fluid systems and products. We employ advanced CFD analysis to solve problems involving fluid mixing, multiphase flow, phase change, non-Newtonian fluids, and microfluidic effects.
Fluidic Mixing

Veryst has deep expertise in fluidic mixing processes, which we leverage for our clients across industries.  A fundamental aspect of mixing is the stretching and folding of the interface between initially separated substances.  This occurs in many forms and systems:

Fluid–Structure Interaction
Fluid-structure interaction refers to the analyses involving simultaneous fluid flow and solid deformation.  Veryst Engineering has worked on a wide range of FSI problems of different complexities. 
Veryst offers a comprehensive approach to solving problems in microfluidic device development.  We employ an array of modeling tools, such as scaling arguments, analytical formulas, computational simulations, and laboratory testing to inform the design and integration of common components.
Multiphysics Modeling
Accurate simulation of many products now requires a multiphysics approach. Veryst Engineering specializes in multiphysics problems involving solids, fluids, heat transfer, mass transfer, acoustics, and electromagnetics. Our modeling and analysis expertise includes fluid-structure interaction, thermal-structure interaction, structural-acoustic vibrations, conjugate heat transfer, Joule heating, and microwave heating.
