Projects / VULCAN


VULCAN (Viscous Upwind aLgorithm for Complex flow ANalysis) offers computational fluid dynamics for subsonic speed through hypersonic turbulent reacting and non-reacting flows on a variety of serial and parallel computational platforms. The computational cost of propulsion flow analysis is reduced through the use of special turbulent wall treatments, multi-grid methods for elliptic and space marching schemes, and conditioning of the governing equations to reduce numerical stiffness. Physical modeling capabilities are improved through the inclusion of models for compressibility, Reynolds stress anisotropies, turbulent diffusivity, finite rate chemistry, and turbulence/chemistry interaction effects. VULCAN can simulate two-dimensional, three-dimensional, or axi-symmetric multi-block problems.
