摘要

A ship design with boundary layer alignment device (BLAD) aiming at improving therninu001dow of a propeller is evaluated using a RANSE computation with adaptive grid reu001cnement. Thisrnpaper is focused on model scale simulation for which experimental results can be used for validation.rnPropeller performance is evaluated with a RANSE/BEM coupling procedure. Numerical simulationrnreveals that adaptive grid reu001cnement is an eu001ecient way to obtain a reliable prediction for suchrnconu001cguration. Moreover, grid reu001cnement criterion is found to be of crucial importance. The newlyrnproposed smoothed pressure Hessian is capable of evaluating correctly the impact of the BLAD onrnthe performance of the propeller.
