【摘要】:The Computational Fluid Dynamics(CFD)approach is adopted to study the steady and unsteady performances of the podded propulsor by the Fluent software package.While the interactions of the propeller blades with the pod and strut are time-dependent by nature,the mixing plane model is employed firstly to predict the steady performance,where the interactions are time-averaged.Numerical experiments are carried out with systematically varied mesh sizes to investigate the dependence of the predicted force values on the mesh sizes.Furthermore,the sliding mesh model is employed to simulate the unsteady interactions between the blades,pod and strut.Based on the numerical results,the characteristics of unsteady hydrodynamic forces are discussed,and the applicability of the mixing plane model is investigated for puller-type podded propulsor.水利论文fijJ(b'rq.s
