船舶高速前进时，船用螺旋桨表面会出现多种类型的空化现象，导致螺旋桨性能下降和/或螺旋桨损坏（侵蚀）。因此，更好地理解空化形成以及预测它们的能力对于成功的螺旋桨设计非常重要。本文给出了特定螺旋桨吸力面发生空化的图像结果，并对这些图像进行分析，以获得空化的统计参数，如空化的大小、位置和占用面积。这些实验结果用于评估相关 RANS 模拟的准确性，以便识别此类模拟中常用的湍流和空化模型的问题。
Multiple types of cavitation appearing on the surface of a marine propeller when the ship advances with high speed cause the decline of the propeller’s performance and/or damages (erosions) to the propeller. Therefore, better understandings of the cavitation formations and the ability to predict them are important to a successful propeller design. This paper presents image results of cavitation incurred on the suction surfaces of a specific propeller and analyzes these images to obtain the statistical parameters of cavitations such as their sizes, locations, and occupied areas. These experimental results are used to evaluate the accuracy of the associated RANS simulations in order to identify issues of turbulence and cavitation models commonly used in such simulations.
