This study employs the open source cfd solvers su2 and openfoam to simulate the incompressible, unsteady, and turbulent flow around an h type darrieus vawt in two dimensions. To this end, we propose two alternative cfd formulations for simulating two phase non ideal compressible flows of sco 2, comparing in detail their physical assumptions and numerical aspects. This work develops data driven metrics to evaluate numerical scheme performance for complex compressible flows. these metrics are then integrated into machine learning ap proaches to systematically optimize scheme parameters. Both approaches are simpler to design and implement when the flow is linearized about the free stream conditions in the neighborhood of the artificial far field boundaries.
