摘要

Based on the coordinate transformation formula for transforming thernlocal to the global coordinate, this paper builds the 3D modeling of thernskewed propeller by UG software. Dispose the propeller locally for thernconvenience of numerical calculation, and gridding the flow field ofrnpropeller. Lastly calculate the performance in open water of propellerrnby FLUENT software, and compare the results between calculation andrnexperiment. Based on the research, the calculations of the performancernin open water of propeller by CFD is good, and meet the engineeringrnrequirement.
