Intake Valve and Feliks' ideas

[Feliks]

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.

About something that you think?

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 !

Interesting feliks.

Excuse me, but why is not the fan inside the venturi? Just for maintenance or something like that?

Excuse me, but why is not the fan inside the venturi? Just for maintenance or something like that?

First, it does not overshadow the venturi its surface, so air flow is facilitated by the venturi. Besides the construction and servicing of a fan with an electric generator on the surface it look easy....






This is Homer. Now you can safely drink, because he knows the underground fan will give him a lot cheaper green energy.
It can use an underground windmill used an old engine, for example, the Harrier. Or the same fan.

"The gain in kinetic energy resulting from the increased linear velocity in the throat is offset (i.e., balanced) by the decrease of pressure in the throat. The reduction in pressure which occurs when the fluid flows through the throat is called the Venturi effect and is named after the Italian physicist Giovanni Battista Venturi (1746 - 1822) who first observed the effect."

It is proposed to be called Venturi widmill: " The Cube Turbine "

Do you know that such a large cooling towers at power plants are made of reinforced concrete walls with a thickness of 12 cm on average?

I'm very curious if that work well, though for that tip wentturi Inject and burn some fuel.
The calculations on the calculator Venturi, that, if the temperature of the air flow would be about 60 degrees Kelvin higher, the speed of the jet that increased by 50% !

If this is not too much to add, that was such a low temperature turbine engine
During low-wind, he could give a little energy.
It was like a ramjet engine

Well, such a complete install on the mountain. Would give as much energy as the whole of Poland produces.

It occurs to me that if one poured petrol into the ground-level fan, and put a spark-plug in the tail pipe of the nozzle, then the mountain could - finally - come to Mohammed...

Lesson Two: in terms of fundamental historical

Venturitubes 1937.pdf

On the pictures below you can see how small the venturi nozzle is to drive the gyroscopes in the strands. My finger and applied on the next hand, illustrate the size of the venturi tube. It is almost equal to the diameter of my finger. Now, please imagine how much energy to give the fan with the same diameter of my finger...








Since the narrowest point of the venturi tube, we can easily get up to 10 times higher air velocity, we can mount the engine behind the jet frame, which at high speeds the inlet has a good performance.
For example, you can mount an engine on an Tourist Plane, which reaches 200 km / h at the entrance to the RAM JET would be about 2000 km / h....
This will generate additional good sequence, using a very simple engine ( or two )

A venturi tube so small as my finger is able to propel a large heavy rotating disk gyroscope air to 10 000 RPM, and even walk through the air filter....





Since the gyroscope can be power, relatively high compared to the diameter of the venturi tubes (1 ") and he has the 2 ", then maybe you can do in F1 KERS Venturi "?
The air sucked into the engine can be sucked through a venturi tube so, resulting in a negative pressure to drive the gyroscope, which will keep energy....

That would be something like a turbine gives energy, but the intake pipe. Turbo
