摘要

这项工作的目的是通过计算模拟来评估水平轴动能水轮机（HAHKT）在使用各种几何配置的扩散器时的结构完整性。这项研究采用流固耦合（FSI）技术，将 CFX 和机械结构耦合到 Ansys Workbench V18.2 中，根据在流体力学层面获得的结果，对由三个叶片组成的 HAHKT 进行了结构分析，叶片轮廓为 NREL S822。使用第三代扩散器时，叶片的最大应力增加了 27%。

Structural Analysis of a First, Second and Third Generation Horizontal Axis Hydrokinetic Turbine

The objective of this work is to evaluate through computational simulation the structural integrity of a horizontal axis hydrokinetic turbine (HAHKT) when using various geometric configurations of diffusers. This study was carried out by fluid -structure interaction (FSI) sing Ansys Workbench V18.2, coupling CFX and mechanical structural, in which a structural analysis was carried out based on the results obtained at the hydrodynamic level of a HAHKT composed of three blades with profile NREL S822, which was also analysed under the implementation of two geometric diffuser configurations. The maximum stresses in the blades increase of 27 % using the third-generation diffuser.
