Computation of Tip Vortex Flow of A Marine Propeller

摘要

The tip vortex flow of a marine propeller at the steady state has been computed based on the RANS solutions with ANSYS-CFX.rnThe spiral-like computational domain is set up as one blade-to-blade passage with two side boundaries/periodic boundaries. The grid is formed by following the inlet flow angle so that the clustered grid can be aligned with the tip vortex.rnValidation studies have been carried out for the DTMB 5168 propeller model at the steady state. The k - ε turbulence model was used in the computation. The computed velocity components in the flow field were compared with the experimental data.
