The control effect of 3D spiral wind-curtain generator on …
Before the 3D spiral wind-curtain generator was used, the respirable dust gradually diffused from the cutting face to other spaces of the tunnel, and finally presented a stable state with time. After using the 3D spiral wind-curtain generator for auxiliary ventilation, the dust diffusion speed in the tunnel was slower than before, and the dust concentration was …

What Is A Helical Wind Turbine?
The helical wind turbine is an odd-looking piece of green technology that harnesses the power of the wind to generate electricity. In the vast majority of instances, the design of the helical wind turbine incorporates a spiral of some kind. These turbines frequently have the appearance of enormous drill bits or DNA helixes pointing upward.
US20180142669A1
the inventor recognized that since a blade unit having spiral blade units the ratio of area receiving wind within the blade''s rotational region is very large than a blade unit having regular blades, if the wind gets stronger, a problem can happen that each blade generates a bending deformation and serious vibration generates due to unbalance of forces on …
Shape optimization of a shrouded Archimedean-spiral type wind …
In such instances an Archimedean-spiral type wind turbine (ASWT) which is a new kind of horizontal-axis wind turbine maybe used for small-scale applications including off-grid power. The ASWT performance is improved in this work by designing a shroud with a flange at its inlet during an optimization technique aims to maximize the …

Australia''s vast landscapes and coastal regions offer an abundance of wind resources, making wind energy a promising option for sustainably-minded homeowners. For those who are considering harnessing the power of the wind to generate clean electricity, investing in a residential wind turbine can be a game-changer. In this article, we will explore the …
Experimental and numerical investigations of the blade design effect on Archimedes Spiral Wind Turbine performance …
Ostia et al. [19] presented a comparison between Archimedes Spiral Wind Turbine and Savonius Wind Turbine. Results indicated that the Archimedes wind turbine had higher RPM and generated more voltage and power with approximately more than 50% of the same wind speed than the Savonius wind turbine when operated individually.
The control effect of 3D spiral wind-curtain generator on respirable dust pollution during tunnelling …
The respirable dust pollution produced in the cutting process of tunnelling machine during tunnelling process is a serious threat to the health of workers. The key to solve this problem is to build an effective ventilation system in the tunnel. In this paper, experiments were designed and implemented to obtain the temporal–spatial evolution of …
