This paper presents development of hyperbolic Navier-Stokes (HNS) systems for three-dimensional viscous flow in edge-based cell-vertex unstructured solver, i.e. Stanford University Unstructured (SU2) platform. Numeric scheme and operation for isothermal wall and symmetry boundary are proposed. For validating the new solver, low Mach flows over two-dimensional NACA0012 airfoil and three-dimensional DLR-F6 wing-body are simulated. The results demonstrate the superiority of HNS over conventional Navier-Stokes (CNS) systems in prediction accuracy of friction coefficient and efficiency. In general, HNS can handle the low-Mach high-Reynolds real flow effectively and efficiently.
