Computational Fluid Dynamics (CFD)
KEI Expertise in CFD
Computational Fluid Dynamics (CFD) is a powerful tool used to predict fluid behavior for a variety of problems including internal and external flows, single- and two-phase incompressible flows, laminar and turbulent flows, and subsonic or supersonic compressible flow. CFD predictions can be used in place of expensive experimental testing, and often reduces overall development cost and time. CFD can be used to provide insights into the flow field. These insights are useful in design refinement and in the prediction of flow-induced pressures and forces for component analysis.
Because CFD models use several approximate models to simulate complex phenomena, obtaining accurate predictions relies heavily on highly experienced personnel. Proper selection and use of these models requires a sound understanding of the underlying physical nature of the complex phenomena.
Validation of CFD Predictions
KEI has independently verified and validated (V&V) CFD predictions against known solutions. The V&V process is used to determine the applicability of several model selections and accompanying settings. These determinations ensure that those models and their inherent limitations are understood. The V&V process provides the end user with a high degree of confidence that the CFD predictions are correct and that they adequately predict the true nature of the flow.
When advantageous to the client, KEI has the ability to perform CFD and experimental testing to provide both predictions and test results.
