Computational Fluid Dynamics


What is CFD?
Computational Fluid Dynamics (CFD) refers to the numerical solution of the partial differential equations governing fluid flow (in this case, the Reynolds-averaged Navier-Stokes equations). With modern computing resources, CFD is frequently used today to obtain accurate predictions of flows over, or through, complex configurations. However, generation of a suitable computational grid can still require weeks or even months on complicated three-dimensional geometries. Once a suitable grid is obtained, many solvers encounter difficulties in achieving a valid solution on complicated geometries.


Corvid’s Advantage
Corvid personnel use and develop tools to improve the entire CFD analysis process, from problem setup to interpretation of results. These tools include:

  • The ANSYS ICEM CFD package for unstructured grid generation
  • Established processes to generate high-quality grids rapidly (0.5 days to 1 week) on complex configurations
  • In-house-developed tools to improve overall grid quality and increase local grid refinement
  • The RavenCFD flow solver, developed at Corvid
  • In-house-developed post-processing tools to simplify the analysis of large 3D datasets
  • FIELDVIEW for dataset visualization
