FSI (Fluid Structure Interaction)

Aerostatic bearing

This example models a jet acting on a bearing. This jet creates a thin layer of air between the bearing and the support. The force acting on the bearing permits to compensate the gravity force.
The figure represents the jet with arrows indicating the direction of the flow. It can be seen that a vortex is created between the bearing and the support. Particles Tracking (coming from the jet) has been used to visualise this vortex.
This application has been solved with OOFELIE coupled with FINE™/Hexa.

Compressible flow in a duct with a moving part

This example models a 3D duct whose upper part has can oscillate. The fluid flow is supposed compressible. The Von Mises constraints are represented on the structure and the velocity field is plotted in the fluid domain.
This application has been solved with OOFELIE coupled with FINE™/Hexa.

Flow around a fixed wind turbine

This example illustrates a thermodynamic flow deforming the blades of a wind turbine. The blades are here supposed fixed and are oriented perpendicular to the inlet flow (the worst configuration). The figures represent the deformation of the blades, the temperature and the velocity of the fluid, as well as the streamlines behind a blade. It can then be seen that two vortices are created behind the blade, and that the fluid goes down.
This application has been solved with OOFELIE coupled with FINE™/Hexa.

Flow around a moving wind turbine

The same configuration as the previous one has been used but the wind turbine is now moving with a prescribed rotation speed, and the blade are now oriented in the direction of the flow. The figure illustrates the flow field with arrows (the fluid is moving according of the blade movement) and the deformation of the blade (the non-deformed blade is represented in blue).
This application has been solved with OOFELIE coupled with FINE™/Hexa.

Incompressible flow in a deformable duct

The first application illustrates an incompressible flow inside a deformable duct. The modification of the pressure along the duct (due to its irregular geometry) induces deformation of the structure (amplified on the figure). This computation has been made with OOFELIE alone (monolithic equations).

Micro-pump

This example illustrates a model of a micro-pump actionated by a piezo-electric material on its top part (fluid-piezo-electric computation). The contraction of the structure can make the fluid goes in or out the pump.
This computation has also been made with OOFELIE alone (monolithic equations).

Thermodynamic computation in a duct

This second example illustrates the flow in a complex duct with temperature imposed on some parts of the boundary. The structure is deformed due to the fluid flow, and due to the modification of the temperature at the boundary where it is not imposed (dilatation of the duct).
This computation has been made with OOFELIE alone (monolithic equations).
