To increase the wind hiting my windmill, can I build a structure (valley, funnell)?

Question

How far in front should this wind-enhancer be to have the vortex-effect hit the blades at the right spot? Where would I want to paint black and where silver?

Answer 1

You'll want to avoid turbulence, it will tend to damage the turbine.

Trouble is, even with an ideal funnel (reverse nozzle?), a strong wind storm will blow it away, or damage it. If it is strong enough to withstand high winds, then it will be expensive, heavy and more difficult to rotate it with changing wind direction.

If you need more power you can get another turbine, or a bigger one.

You can also put it on the roof of a building, an equal distance above the roof, as the roof is from the ground. The building will deflect the wind and create a higher velocity above the building, but you need to locate it high enough, and in the right spot to minimize turbulence and vibration.

Answer 2

I'm presuming 3 things:

1) you have the top-of-the-line $3 million windmill with the super long blades. Only then would investing in a wind funnel be commensurate with its associated cost.

2) your windmill is situated where the prevailing wind strikes from the same angle over 90% of the time due to topography. So you are looking for a terrain enhancer to further funnel the wind.

3) since wind is described as a consequence of the irregular heating of the earth's surface, you want to paint the pavement black in certain areas and white in other areas to further escourt the wind.

If the above presumptions are accurate then I suggest:

1) Situate the windmill at the tail end of two hills where gusts of wind barrell down the valley. Create a roller-coaster type ramp (45 degree incline, supported by stilts), the runway shaped like a trough ("u" shaped). The mouth would terminate just inches away from where the blades reach their lowest point.

2) Check wind erosion and other clues, including, of course, instruments to measure wind direction during all seasons. Make darn sure of the prevailing wind before going through the expense of building a contraption to further direct the wind (funnel).

3) Paint the area before the runway for as long as possible back in black. The width should be at least that of the runway. The actual runway trough should be black with silver lining the inner sides at an angle to reflect down to run down the center. The trough needs to swivel -- in order to tilt east and west. I presume the upramp is facing the sun, since that is what would have caused the prevailing wind to come about in the first place anyway.

Answer 3

i'm presuming 3 issues: a million) you have the proper-of-the-line $3 million windmill with the large long blades. in easy terms then might making an investment in a wind funnel be commensurate with its linked fee. 2) your windmill is located the place the winning wind strikes from the comparable perspective over ninety% of the time via topography. so which you're finding for a terrain enhancer to added funnel the wind. 3) on condition that wind is defined as a results of the unusual heating of the earth's floor, you desire to paint the pavement black specially areas and white in different areas to added escourt the wind. If the above presumptions are precise then I advise: a million) Situate the windmill on the tail end of two hills the place gusts of wind barrell down the valley. Create a curler-coaster sort ramp (40 5 degree incline, supported via stilts), the runway shaped like a trough ("u" shaped). The mouth might terminate merely inches far flung from the place the blades attain their lowest factor. 2) examine wind erosion and different clues, that's composed of, of direction, contraptions to degree wind direction for the time of all seasons. Make darn beneficial of the winning wind earlier entering into the path of the fee of establishing a contraption to added direct the wind (funnel). 3) Paint the section earlier the runway for as long as available back in black. The width could be a minimum of that of the runway. the relatively runway trough could be black with silver lining the indoors aspects at an perspective to mirror right down to run down the middle. The trough needs to swivel -- with the intention to tilt east and west. I presume the upramp is dealing with the solar, on condition that that's what might have brought about the winning wind to come approximately in the 1st place besides.

Answer 4

What ever you construct would necessarily have to rotate with your wind mill to accommodate different wind directions.

I'm quite confident that there has been extensive research done on this idea - and the resulting designs with the best efficiencies to date all seem to rely on longer, lighter blades.

You can experiment with different blade pitches and widths and so forth - but I have never seen a windmill with any type of valley or funnel on it.

You may be on to something with your vortex idea - before the effects of vortexes were known, it was pretty much decided that a bumble bee couldn't fly (body mass too large for the wing area). I've read that with certain building designs, vortexes have actually caused shattered windows and minor structual damage.
