Kurzfassung
The discretization of the incompressible Navier-Stokes equations leads to a saddle-point problem in which the discrete equations for the pressure and momentum are coupled. Traditionally, this coupling is solved by segregated methods in which separate equations for momentum and pressure are solved with the constraint of obtaining a divergence free velocity field. In the coupled approach a single block system of equations for the momentum and pressure is formulated and solved simultaneously. Furthermore solution of such a coupled system has been shown to improve robustness and convergence properties. In the present work, a coupled approach for the solution of incompressible Navier-Stokes and RANS equations have been developed in the finite volume framework of the CFD software CODA (CFD for ONERA, DLR and AIRBUS). The implementation is verified and validated with various test cases.
