Abstract
Within EU Project LEADING EDGE (LE) several RANS solvers have been applied for predicting the performance and flow patterns around marine propellers. The investigation included three propellers: a conventional, a high skewed and an endplate one. The two first propellers were subject to comparative RANS studies among the LE partners. VTT independently analyzed the third one. A summary of the results for the endplate propeller analysis is presented here. Special emphasis is set on describing the flow over the endplate. The flow is simulated using solver FINFLO. FINFLO is a multi-block cell-centered finite-volume computer code with sliding mesh, moving-grid and free-surface capabilities. Computations are made at model and full scale using the k- turbulence model. Relative differences between calculations and experiments are presented for performance coefficients in open water condition at model scale. Good correlation with experiments is obtained in terms of overall forces. The calculated flow patterns over the endplate of the propeller are illustrated for one advance number.
