Modelling of flow around a marine propeller using a potential-based method
Résumé
A nonlinear method is presented for calculating potential flow around lifting bodies. The perturbation potential is taken to be unknown at the surface of the body while its value is fixed inside the body. This method is particularly well suited to cases of thin structures. It is applied to calculate the flow around a non-cavitating marine propeller for which several difficulties are examined and solutions proposed: problem of the Joukowski condition, problem of propeller mesh, wake description. The influence of the hub and the calculated wake on numerical results is analysed.
