Computational Fluid Dynamics (CFD)
Gain a competitive advantage by reducing design failures and optimizing engineering design with our Computational Fluid Dynamics (CFD) consulting and simulation services.
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.
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 (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 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.
