Application of the dynamic mesh method in the numerical simulation of unsteady bearing forces of a propeller
摘要
Abstract
The applicability of the Dynamic Mesh (DM) method in numerical simulation of propeller Un⁃steady Bearing Forces (UBF) is studied in this paper. The grid independence is initially verified by compar⁃ing three sets of grid of different qualities and the most suitable set of grid is selected for the work. Further numerical simulation is conducted by adopting DM method, and the corresponding results are compared with those obtained from the Sliding Mesh (SM) method, Potential Flow (PM) method and experiments. The analysis indicates that for the various characteristics of a propeller UBF, the results of the DM method are consistent with those of the SM method and experiments, and are better than those of the PM method. Mean⁃while, the flow field distribution obtained from the DM method agrees well with that from the SM method. Therefore, the application of the DM method in the numerical simulation of a propeller UBFs is feasible and effective.关键词
