FPVortex™ is a Computational Fluid Dynamics (CFD) flow solver capable of computing aerodynamics and multi-phase, chemically reacting flows in and around complex geometries. Large-scale simulation examples covering a wide range of industrial applications are shown below, all computed using FPVortex™ and run on a PC.

The three combustion simulations above are 3-D turbulent, chemically reacting flows at full temperature and pressure operating conditions. The aerodynamic cases on the second row are turbulent flows, with the supersonic cascade flow computed with an adapted mesh for superior shock wave resolution. In each case, geometry definition is obtained from a CAD solid model, which is then used for automated grid generation, and is output in an unstructured database format. The physical models used in these simulations include the standard two-equation k-ε turbulence model, and the eddy breakup combustion model. Also available in FPVortex™ is the Lagrangian spray droplet dynamics model with evaporation. The advanced grid adaption capability provides exceptional resolution of important flow features such as shock waves, flame fronts, and fuel-air mixing surfaces.
Advanced physical models and numerical algorithms developed at the NASA Glenn Research Center (GRC) are available in FPVortex™ through a Space Act Agreement (SAA) between NASA and Flow Parametrics, LLC. Examples of advanced models include: Intrinsic Low Dimensional Manifold (ILDM) methods for chemical kinetics; Probability Density Functions (PDF's) for turbulent-chemistry interactions and turbulent mixing; and advanced forms of turbulence model including non-linear and low-Reynolds number versions of the standard k-ε model. The implementation of advanced models and specialized boundary conditions can be tailored directly to customer needs.
