SETUR​ TURBINES

Eco-friendly turbine SETUR harnesses energy of low velocity / low hydraulic head water sources as ocean currents, tidal streams, rivers, canals and other sources of hydrokinetic energy.

Turbine SETUR uses vortex phenomenon to generate energy. It can be cost-effectively used either as a standalone self-contained system or within a multi-unit hydro power farm.

Several modifications of turbine have been successfully tested over the years and we now offer its most advanced version.

Since 2008 SETUR turbines have won several prestigious international awards, including E.On Energy Globe Award 2014.

TECHNOLOGY

The rotor and the stator create in a quiescent state a symmetrical coaxial diffuser as shown in Figs. 1 and 2. However, this state is unstable and as a consequence of the instability of the flow through the gap between the rotor and the stator it changes to an asymmetrical one. The shape of the rotor and stator can be variable i.e. it might be improved or optimized. In practice the most common rotors are hemispheres as in Fig. 1, but what really matters is the diffusion angle of the gap between the rotor and the stator.

One tip of the rotor’s shaft is fixed, so that the rotor can roll along the inner side of the confuser. When the fluid flows along the rotor, then due to the flow field instability, the fluid starts to rotate and vorticity is generated. The direct consequence of the vorticity generation is the onset of velocity circulation and the force interaction between the fluid and the rotor. This fluid structure interaction results in the rotation of the shaft on which the rotor is placed.

Fig  1. Initial position of the rotor and deviated position of the rotor in motion. This shape of rotor is usual for contemporary turbines in praxis but on the other hand for theoretical analysis conical shape is more suitable.

In principle it does not matter if it is hanging or supported. The rotor with the shaft then performs a precession movement and rotates (circulates) around its direct axis. The amount of rotation depends on the ratio between the inner and outer radii. When this ratio is close to one, i.e. when the gap between the cylinder is small, the number of precessions needed for one rotation of the rotor around its axis increases as the width of the gap decreases. The number of precessions can be simply changed by changing the width of the gap. In the case of a conical stator this can be done by changing the vertical position of the rotor.

The first embodiment of rolling turbines used a rotor hanging from the entry part of an outlet nozzle. The diameter of the rotor for example can be just several centimeters or millimeters. Water flow rates can change usually from single liters to hundreds of liters per second.

The advantage of such turbine lies especially in its simplicity, environmental safety and ability to operate in ultra low sources of water. The turbine design allows easy adjustments as might be required by specific applications.

Fig 2. Simplified scheme of the turbine. Fluid flows between the inner cone and the outer cylinder.

In practice more complicated shapes of the rotor and stator have been developed but this figure shows the most important feature of the turbine, the diverging non-symmetrical gap crucial for the appearance of volume forces responsible for the rotation.
