Blade trailing edge position influencing pump as turbine (PAT) pressure field under part-load conditions
The study seeks to investigate the effect of the blade trailing edge hub position on the pressure field characteristics within a centrifugal PAT (Pump as Turbines). Using the k-ε turbulence model, unsteady numerical simulations were carried out on three centrifugal PAT designs with different blade trailing edge hub positions.
