The Reynolds-averaged Navier-Stokes (RANS) method, along with the Fluent software package, was used to study the steady and
unsteady interaction of propellers and rudders with additional thrust fins. The sliding mesh model was employed to simulate
unsteady interactions between the blades, the rudder and the thrust fins. Based on the numerical results, the pressure distribution
on the propeller and the efficiency of the fins were calculated as a function of the attack angle. The RANS results were compared
with results calculated by the potential method. It was found that the results for the potential method and the RANS method
have good consistency, but they yield maximum efficiencies for the fins, and thus corresponding attack angles, that are not
identical. 相似文献

A 2-D laminar flow model was established for CFD analysis of air-flow between louvered fins. Two louvered fins are studied based on commercial software FLUENT. Air-flow pressure drop characteristics are derived on the calculation of Reynolds number from 75.3 to 600.The numerical results are in good agreement with the experimental data when Reynolds is lower. 相似文献
