You, RuiRuiYouKinnas, Spyros A.Spyros A.Kinnas2024-04-122024-04-122024-04-048th International Symposium on Marine Propulsors (smp 2024)978-82-691120-5-4https://hdl.handle.net/11420/46498This paper extends the 3-D VIScous Vorticity Equation (VISVE) solver, originally designed for laminar flows, to address turbulence. By incorporating a 푘 − 휔 SST turbulence model via the Finite Volume Method (FVM), the study aims to develop an efficient tool for analyzing propellers under realistic, turbulent conditions. The developed turbulent VISVE solver was applied to a 3-D NSRDC 4381 propeller with 5 blades. The VISVE method, with its spatially concentrated vorticity, allows for a highly efficient computational approach, significantly reducing computation time. The developed numerical model was validated with a Reynolds-Averaged Navier-Stokes (RANS) solver. Comparative analyses reveal substantial alterations in velocity and vorticity distributions between laminar and turbulent cases. Turbulence introduces complex flow patterns and thinner boundary layers, which the 푘 − 휔 SST turbulence model captures. The extension of the VISVE method enhances predictions of propeller performance under realworld operating conditions. This study emphasizes the importance of considering turbulence in propeller analysis and design, providing a computational tool for this problem.enhttp://rightsstatements.org/vocab/InC/1.0/Viscous Vorticity EquationTurbulence ModelingPropeller3-DTurbulent flowEngineering and Applied OperationsA viscous vorticity model for predicting turbulent flow over a propellerConference Paper10.15480/882.936110.15480/882.9361Conference Paper
