摘要
Numerical simulation method of propeller tip vortex and tip vortex cavitation (TVC) was researched by calculating the propeller model of Potsdam Propeller Test Case (PPTC). Through the partition of tip vortex field and the refinement of the field gridding, non-cavitating flow around PPTC was simulated and tip vortex was successfully captured. Then the cavitating flows were calculated based on the homogeneous mixture flow model and the Zwart-Gerber-Belamri cavitation model. Comprehensive analysis of computational results and comparisons with EFD data were done to validate the computational mesh and method. The good agreement between the calculated and observed cavitation was found for both tip vortex cavity and sheet cavity. The calculated thrust and torque coefficients agree with the EFD data as well. The tip vortex and tip vortex cavitation were both numerically captured. And it is shown that the nucleation site volume fraction has more effect on the thrust and torque coefficients than the cavity patterns. © 2019, Editorial Board of Journal of Ship Mechanics.
