Abstract
En 中文
•
A large CFD database is developed to investigate numerically the propeller scale effects and improve traditional extrapolation methods.
•
Results show that ITTC scaling approaches agrees only with the trends of the frictional component of thrust and torque from CFD calculations.
•
ITTC scaling fails to capture significant pressure-driven contributions highlighted by the CFD simulations.
•
Pressure strongly influence thrust and torque scaling, leading to non-monotonic trends and, sometimes, higher full-scale torque.
•
Findings highlight the need for data-driven scaling methods accounting for combined frictional and pressure effects.
