The present problem simulates the water flow around a vertical-axis water turbine submerged in water using the dynamic mesh method in ANSYS Fluent software. The water turbine is from the category of vertical axis turbines and is of the darrieus type; So that the axis of the turbine is perpendicular to the direction of water flow. For this simulation, a vertical axis turbine with three blades is designed within a relatively large computational area in which the computational area has only water flow. In this simulation, it is assumed that the vertical turbine is rotating in the water flow, and therefore, this rotational motion of the turbine blade body affects the surrounding meshing.
So that it causes instantaneous and time-dependent change in meshing based on the type of displacement at adjacent boundaries of cells. Therefore, the dynamic mesh model is used to define the instantaneous change of meshing around the rotating turbine blades. To better define the dynamic mesh, a cylindrical area is separated from the entire computational area, so that this area includes the turbine blades. Now, to define the areas under the dynamic mesh, the walls of the turbine blade body, as well as the differentiated area around the turbine blades, are defined as Rigid Body.
