Evaluation of Propeller Inflow Improving Device with Adaptive Grid Refinement Computation
Résumé
A ship design with boundary layer alignment device (BLAD) aiming at improving the inflow of a propeller is evaluated using a RANSE computation with adaptive grid refinement. This paper is focused on model scale simulation for which experimental results can be used for validation. Propeller performance is evaluated with a RANSE/BEM coupling procedure. Numerical simulation reveals that adaptive grid refinement is an efficient way to obtain a reliable prediction for such configuration. Moreover, grid refinement criterion is found to be of crucial importance. The newly proposed smoothed pressure Hessian is capable of evaluating correctly the impact of the BLAD on the performance of the propeller.
