WebMay 6, 2024 · Abstract. Global linear stability analysis of open flows in truncated domains suffers from imperfect boundary conditions, leading to either spurious wave reflections (in compressible cases) or to non-local feedback due to the elliptic nature of the pressure equation (in incompressible cases). A novel approach is introduced to solve such an issue. WebThe general non-reflecting boundary conditions in ANSYS FLUENT are based on characteristic wave relations derived from the Euler equations, and applied only on pressure-outlet boundary conditions. To obtain the primitive flow quantities ( ) on the pressure-outlet, reformulated Euler equations are solved on the boundary of the domain in an algorithm … Web7.4 Non-Reflecting Boundary Conditions.
