QUOTE (Greg Locock @ Mar 29 2011, 21:25)
Step back from the equations, and think about what would happen if you put a disc with a hole in it up to the airflow. Now stretch the disc out along the axis of the hole. All the air in the disc bit will be still 'see' disc ahead of them, not the hole you'd like them to go for. A big wodge of stagnated air will build up ahead of the venturi. For the equations just use continuity and Bernouilli, for the lossless case./QUOTE
In this reasoning, the disc does not have thickness. The reasoning for the classic windmill, to which all are used: flat disk, with virtually no thickness. Therefore, the classic windmill has a low efficiency, because this disc is not dispensed air mass and its speed is only such as wind.
The venturi nozzle are two cones and a not insignificant thickness of 25 meters. And now this whole mass of air that is housed in a venturi nozzle is involved in the flow through it. It should be noted that the cones are of unequal length. Cone output is 30 % longer than the input... why? Well, because this is the output cone of doing it at low pressure in the narrowest point.
With reduction in pressure, is involved the whole mass of air in which the output is a cone, that is, the average disk X 16m. Cone can not be shorter because they do not provide laminar flow, which is a prerequisite for good work Venturi nozzle. With disorders of movement ( for a short cone ) in action will take part, only a small mass of air, to lower pressure. The condition is llaminar flow, because the cone has to be quite so long. For that produces a significant vacuum in the narrowest point, causing fresh air to the input cone...

[quote name='gruntguru' post='4932215' date='Mar 31 2011, 04:21']Unfortunately the very low pressure you imagine does not exist unless you achieve the 64 m/s velocity. There is not enough energy in the wind to accelerate it to that velocity so you won't get the low pressure either.
Conservation of energy.
[/i]Massflow is 40 kg/s not 199. These are high end numbers assuming all the energy in a 6m diameter "sausage" of wind approaching the venturi, ends up in the throat. In reality, the theoretical maximum is only 69% of that (Betz's law) and a real machine will not even achieve that much.

"does not exist " - plane not flying, carburator is not work and Fukushima not dangerous :lol:

If they move to the Thames this venturi nozzle:
D=1 meter, L = 5 meter V min 0,6 m/sec V max 6 m/sec , Flow 500 kg/sec .....
A little power except that she did....
The same goes for the sea tide and sea currents.

So yes, I think it best to start with what everyone has long-standing knowledge and know how not to reinvent the wheel.
Ideally we'll see this in professional.

Feliks, do you think the above ideas could be used on ALL forms of exhasut as a power recovery system do you? just thinking if you could use the energy of the exhaust to drive 'something' then its basically free energy isn't it?
Just thinking on a blighting the view point of view, how high would these need to be mounted?

[quote="hollus"]That Venturi nozzle feeding a windmill-turbine is a really interesting concept.
One of the problems with current windmills is that they must be constantly pointed to the wind, not only to optimize energy generation, but also lest they might sustain some damage.
A set of nozzles, say in a six or eight pointed star arrangement, could feed a fixed windmill, which as you suggest, could now operate in a horizontal plane and be sustained in rails or whatever.
The nozzles, being quite solid structures, can take side winds, and one would just need to open/close the appropriate valves within the nozzle star at the right time depending on the direction of the wind, much easier and faster than rotating a whole windmill with the wind. One could also combine any number of such tunnels and stack nozzles at different heights.
The wind capturing device and the energy generating device become effectively uncoupled from each other.

In the Wikipedia is a big mistake or inaccuracy
Call it what you think.
Now why is that:
Kinetic Energy = Mass x 0.5 x Velocity2 It is certainly true.
But when it comes to the calculated mass is no longer referred to as:
Mass / sec (kg / s) = Velocity ( m / sec ) x Area ( m2 ) x Density (kg/m3 )
In my opinion, if we count the mass, we must indicate the volume of the cylinder, which is in addition to its surface and its length.
Here, due to an error or a" shortcut calculations" assume that the length of the cylinder is equal to 1.
But it is not always true mass depends also on the length of the cylinder, because they can be 50 meters.
Of course, if you will take part in the formation of energy.
Even in a new traditional windmill blade width can have two meter, and now the model is invalid.
But because the masses are Surface x L x Density. Always.
Well, where we have L ?

By the way. What has to calculate the speed of her weight?

Holidays are approaching, so we do spring cleaning. For sure we will use the vacuum cleaner. We can using such a vacuum cleaner to see how the underground windmill will run . Namely, you should close the pipe vacum cleaner is best without the caps to a small fan, for example, to cool the CPU, or a computer power supply. We will have a working model of an underground windmill......
The following picture shows the sports exhaust, which are built with a relatively long individual pipes from each cylinder. Their length L is crucial for their proper operation. Mass departing exhaust with a volume of such tubes will help the new portion of air intake into the cylinder, while the common valve opening. This mass is precisely calculated for the speed at which it will perform a so-called dynamic charge of the engine
Just the energy contained in the exhaust of precision of the volume of the exhaust manifold vacuum in the cylinder does.
Happy Easter to everybody !
