Innovative Wind Energy Generating Device Coupled with Air Convergent

Aims: Researchers are more and more focused on finding ways to optimize renewable energy sources. One of the more promising of these renewable energies is wind energy. However, these wind resources are very localized and selective. There is also significant potential for wind resources available at low densities or low wind speeds. The objective of this research is to exploit these resources.

Methodology: To do so, this study proposes a new wind generating device coupled with a flow convergent in order to increase its performance at low wind speed. This new wind device is designed under Solidworks and analyzed with Matlab software. Several parameters are simulated. The effect of the pulley transmission ratio on the mechanical values of the generator, the impact of the operating gas in terms of angular velocity, power and torque on the generator shaft was clearly determined.

Results: It appears that the power at the input of the wind device is multiplied by the square of the ratio of the output and input velocities, the flow passing through the convergent being constant. The torque on the generator decreases with the increase of the transmission ratio while its speed increases. However, for a fixed transmission ratio, the speed remains constant while the torque and power increase with the speed at the inlet of the convergent. On the other hand, it is noted that, the lower the adiabatic coefficient of the gas used, the higher the power generated.

Conclusion: When used with a wind device, the output parameters of the convergent will result in better mechanical efficiency, which greatly improves electrical power generation.
