... prediction calculation was based on the Kutta-Joukowski theorem. The results show reasonable agreement with the numerical prediction tool XFOIL and they follow the expected trends across all operating conditions. These findings suggest that this methodology might be expanded to conduct hydrodynamic analyses...

... flow. Viscous flow solvers have been shown to provide adequate predictions for transom flows, however the time and computational cost of these high-fidelity calculations tend to be extremely high. The separation, and eventual ventilating, are viscous processes, thus potential flow solvers are unable...
