Aerodynamics of wind turbines

The unsteady aerodynamics of wind turbines can be easily analyzed in XFlow's virtual wind tunnel. The rotor is allowed to spin freely depending on the torque exerted by the wind. Thus with the simulation it is possible to assess the efficiency of the turbine and predict loads on blades, wake's turbulence intensity, or interference effects in wind farms.

Natural convection

XFlow thermal solver allows to simulate problems driven by natural convection for energy applications, such as the solar tower.

In this case, the air contained in a collector is heated by the sun. The resulting natural convection causes air to rise up the tower and to move a turbine, which produces electricity.

Free surface

Rigid body dynamics can also be coupled to free surface flows. For example the water wheel is allowed to rotate freely around its horizontal axis due to the torque provided by the flow when water strikes the paddles.
