Computational Fluid Dynamics (CFD).

Computational Fluid Dynamics (CFD) is a technology for quickly and accurately solving complex fluid flow and heat transfer problems computationally. Our CFD consulting services enable product design teams to reduce the risk of design failures and to optimize engineering design. Design teams utilizing CFD analysis are 20% more likely to meet product launch date targets than those that don't. Explore the many applications of CFD below.


Using the latest CFD software, Creaform excels at all types of Computational Fluid Dynamics simulations—no matter how complex or critical your project is:

 Steady state and transient CFD simulations of internal/external liquid and gas flows

Analysis, design and optimization of immersed or surrounding components

  Optimal turbulence modeling approaches: RANS, URANS, RSM, LES, DES

 Incompressible, transonic and compressible flows

 Rotating equipment and moving bodies

 Multiple reference frames, rotating and sliding interfaces, deformable meshes

 Fluid-structure interaction

 Heat transfer and thermal modeling

 Multiphase and free surface flows

 Flow mixing

Reacting Flows

Reacting flows are characterized by interacting, multi-temporal complex physical processes for heat, mass and momentum transfer. A range of CFD techniques are used in simulating reacting flow scenarios utilizing detailed models for gas-phase, surface and particle chemistry. A subset of reacting flow CFD modeling is fire and smoke CFD modeling often used in the design of ventilation systems in tunnels and other built environments.

Incompressible and compressible flows

The majority of industrial flows are incompressible and turbulent. Flows at higher Mach numbers can be considered compressible, that is, density can not be considered as independent of the pressure field. Compressible flows require slightly different numerical approaches and are not covered by all CFD software packages. In both cases, simulation accuracy will rely heavily on accurate turbulence modeling.

Fluid-Solid Interaction

Fluid-Solid Interaction (FSI) is a type of CFD modeling that allows for the study of the complex interactions between a fluid and a solid structure. Common applications include floating bodies in water, fluidized bed reactors, and vortex induced vibration.

Convective and Conductive Heat Transfer

Thermal modeling is a key player in today’s engineering world from the design of heat exchangers to the thermal cooling of electronic component. Pictured to the right is the flow through the Barreleye Server chassis, with component coloring based upon surface temperatures


Increasingly engineers want to simulate complex electro-chemically driven processes such as corrosion, fuel cell behavior, flow battery performance and many more diverse mechanisms. Electro-chemistry is routinely modeled in CFD simulations, uniting theories of fluid dynamics, chemical reactions and electric currents.

Multiphase Flows

Multiphase CFD simulations are include interactions of multiple phases within a single simulation, including boiling, evaporation, condensation and freezing. The Discrete Element Method (DEM) and other numerical methods can be used to simulate the motion of a large number of interacting discrete particles such as the granular flow of aggregates

Computational methods developed in structural mechanics, heat transfer, fluid mechanics, electrodynamics and many other fields of engineering can be an enormous aid to understanding the complex physical systems they simulate. Often, it is desired to use these simulations as virtual prototypes to obtain an acceptable or optimized design for a particular system. Recent advances in artificial intelligence and numerical algorithms now allow for not only single-point predictions, but also for automated determination of system performance improvements throughout the product life cycle.

System performance objectives can be formulated to:

 minimize weight, cost, or defects;

 limit a critical temperature, stress, or vibration response

 maximize performance, reliability, throughput, reconfigurability, agility, or design robustness
