Assessment of the λ coefficient in an interface-effect eddy-viscosity correction for unsteady cavitating flow over a Delft Twist 11 hydrofoil
Unsteady cavitation affects the hydraulic performance and reliability of mechanical engineering components such as hydrofoils, pumps, and turbines. Its numerical prediction remains challenging because standard one-fluid RANS simulations may overpredict eddy viscosity in the vapor–liquid transition region and suppress...
