FSI Method for Water Turbine, ANSYS Fluent CFD Simulation Training
The present study investigates the water flow around a vertical water turbine considering unsteady CFD simulation by ANSYS Fluent software. In the present case, it is assumed that the turbine blades are affected by the flow of the passing fluid; that is, the fluid flowing through the turbine blades impedes forces on the turbine body and these forces cause deformation or resizing of the body of these blades. Therefore, the present problem consists of two fluid and solid solutions at the same time and hence, the FSI method and the coupling between the fluid flow and the Transient Structural are used.
Assumptions for Water Turbine CFD Simulation using FSI Method
Simulation is Transient and the solver is pressure-Based. Also, the gravity force effect is ignored.
Geometry & Mesh of the Water Turbine
The present 3-D model was designed by Design Modeler software. The geometry of the model consists of a large cubic space as a fluid domain and the water turbine inside this space as a solid domain. The unstructured mesh was carried out by ANSYS Meshing software. The element number is 523202.
