Verification and validation (V&V) are essential processes in computational simulations that aim to evaluate the accuracy and reliability of the results compared to experimental data. The quantification of error and uncertainty estimates is crucial in V&V. In this particular study, the open water test of a four-bladed B-series propeller model at 1/6.98 scale was conducted for three advanced coefficients (J = 0.50, J = 0.60, and J = 0.70) at the Indonesian Hydrodynamic Laboratory (IHL). The simulation was conducted under experimental conditions using FINE/Marine 7.2. Verification was performed to estimate the error δ_(〖RE〗_G)^* and the numerical uncertainty USN according to the ITTC convergence ratio R and order of accuracy P_G. The average uncertainty estimated for the thrust and torque coefficient was found to be between 1.72% to 4.81%, with a 95% confidence level. Reducing errors and uncertainties associated with verification and validation in open-water experiments can increase the reliability of numerical simulations.
The present study was underpinned by The National Research and Innovation Agency (BRIN) which has provided funding for research-based educational programs, under the grant number SP/112/BPPT/08/2021. The BRIN's commitment to research has been instrumental in enabling the authors to conduct this investigation and disseminate the findings to the scientific community. The authors would like to acknowledge the valuable assistance and support received from the staff members of The Indonesian Hydrodynamic Laboratory, which has significantly contributed to the successful completion of the experiment.
