UNCERTAINTY QUANTIFICATION OF SELF-PROPULSION ANALYSES WITH RANS-CFD AND COMPARISON WITH FULL-SCALE SHIP TRIALS

RANS-CFD is a well-established tool with widespread use in maritime industry and research. Valuable information might be extracted from the results of such simulations terms ship resistance flow field variables. With recent advancements computational power, it became possible to investigate performance ships self-propulsion conditions RANS method. This paper presents study which analyses small size product/oil tanker has been carried out at scale. The methodology proposed this makes open water propeller predictions, model scale computations for minimum 2 different loadings obtain point respective parameters. In order speed up time-consuming computations, these cases have solved single-phase approach. Resistance predictions compared experimental findings. Uncertainty associated prediction thrust quantified. Additionally, sea trials conducted on subject vessel its two sisters measured delivered power data used evaluating capability numerical method predictions. Comparison indicate that computation CFD capable predicting sufficient accuracy an acceptable cost.
