Abstract

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.

第一代、第二代和第三代水平轴水力涡轮机的结构分析
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%。
