| Abstract | Propeller-induced pressures are critical excitations of ship structures and contribute significantly to onboard vibrations. An accurate characterisation of the propeller as a vibration source is essential for reliable numerical simulations of ship vibration. Full-scale measurements are often costly, making model tests an attractive alternative to measure these pressures. This study investigates the propeller-induced pressure distribution on a scaled bulk carrier model in NRC-OCRE’s towing tank under non-cavitating conditions. Twelve sensors above the propeller recorded pressures at various model speeds and shaft rotation rates. MATLAB® and Design Expert 13® were used to process the data and derive polynomial representations of the pressure distribution across the sensor locations and based on different model’s and shaft rotation speeds. The results provide valuable insights into local pressure distribution by introducing explicit pressure polynomials, estimated statistically, and highlighting the model testing as a practical tool for enhancing ship vibration research. |
