COMPUTATIONAL FLUID DYNAMICS (CFD)

Building environments
Over the years, our expertise in the analysis of airflow, heat, humidity and contamination for sensible environments has created significant value for multiple building environment such as bio-pharma facilities, laboratories, industrial enclosures, warehouses, greenhouses, underground environments, server rooms and office buildings. Typical projects will usually target ventilation design, air quality, thermal comfort, humidity control or contaminant control. We have worked extensively on containment strategies for cleanrooms and laboratories, the configuration of refrigerated spaces, identifying gas leaks for assessment of explosive limits or workers’ exposure, improving thermal comfort in offices, and assessing indices of Indoor Air Quality (AIQ)

Heat management
Creaform Engineering uses CFD simulations to design, optimize, certify and troubleshoot heat dissipating products or thermal management systems.
Conjugate heat transfer simulations handle conduction, convection and radiation while accounting for the action of heat sinks, fans, heat exchangers, evaporators, heat shields, etc. We have worked on many projects to address electronic cooling, underhood thermal management, heat exchanger optimization, and the design of power electronics systems.

Turbomachinery
Some of our CFD staff come from the power generation sector and have long-standing experience in turbomachinery simulations. We work on a regular basis with dedicated methods such as pressure jumps, momentum sources, rotating reference frames, mixing-plane interfaces, sliding meshes, overset meshes, etc. We also have a proven track record in CFD applications related to hydraulics, hydrokinetic or wind turbine design, multistage pumps, and fans and blowers.

Food, pharmaceutical and medical processes
Processes in the food and pharmaceutical industry, and especially mixing, benefit greatly from CFD insights. Simulations of mixers for miscible and immiscible liquids, viscous emulsions, solid-liquid suspensions, and shear thinning fluids (non-Newtonian) help with a variety issues, such as inhomogeneous flow patterns and temperature, solid precipitation, prolonged mixing time and power consumption. Thermo-fluid simulations are also used for the cooling of exothermic chemical processes, or even for medical procedures involving heat transfer in human tissues.

Bluff body aerodynamics and wind engineering
External aerodynamics is a traditional application of CFD. Creaform Engineering has created virtual wind tunnels for sports aerodynamics, recreational vehicles, car racing and wind engineering. Our clients entrust us to conduct drag assessments for ground vehicles, ships or planes, validate wind loads on structures, ensure pedestrian comfort or predict snow buildup.
