Innovative micro hydroelectric turbine

[udayprashant]

That looks cool! I have seen a similar pulsing/strike motion effect happening in high pressure hoses that are airlocked!

Do you think a clutch and flywheel could be added to give continuous motion and energy storage?

Best Regards

Thanks for suggestions, I also saw one or two videos of similar thing which are classified as sludge flows where air and water are mixed in common pipe and creates pulsatile flow, but in my demonstrations the whole setup has to be airtight and any air just halts the whole thing permanently.

My goodness. My heart skipped a beat when I saw this! :P

Really interesting and very simple. Those are generally the best ideas. The action so reminds one of the operation of the heart organ, that it nearly takes on a living aspect when you watch it.

I'm going to try and replicate this as soon as possible. Great stuff Uday! And thanks for finding and inviting Ash.

I really appreciate your encouraging comments. I started of initially to develop a easily reproducible model of heart to understand some aspects of hemodynamics in my small lab. Since I discovered these automatic pulsations of very small setup using birthday party balloons and garden hose pipe; for 4 years I was playing with them like some personal toy only without knowing what else it can be useful for.

One day I visited a science meusem and I was so engrossed in mechanics department and when I was travelling late night alone in a bus, suddenly a brainwave struck me and thought may be we can use it as a hydroelectric power generating model.

Another 5 years of my spare time I had spend to design a suitable mechanical model for motion transformation and all my initial models had pendulum tied to the 'U' shaped tube swinging two and fro as the tube swings forward much more prominently then in vertical direction. But they failed to produce sustained and useful moving mechanism for energy conversion.

When I decided to do some measurements I recorded very widely fluctuating pressures in the 'U' shaped tube changes occurring in short span of milliseconds and then I resaoned out it must be repeated water hammers occurring inside the tube which was powering the oscillations, while all the time I was thinking that the collapsing bladder imparts force to those oscillations.

Further research on fluid transients in bend tubes with elastic supports lead me to design the present simpler version wherein the tube is coupled to a spring with correct spring constant and then I could get sustainable, predictable and stable energy conversion.

I think these are whole set of new oscillators similar to Veljko Milkovic oscillator where gravitational oscillations are combined with elastic ones.

[MonsieurM]

You are quite right, the reason i thought of Veljko Milkovic oscillator when i saw your video was the frequency by which your apparatus oscillated looked "similar" to Veljko Milkovic oscillator's movement pattern.

Hi all

Thank's very much Dr Prashant for giving us this wonderfull idea.

I made a crude replication and it works at once and very nicely. I was so surprised that i could not prevent me to have a good laugh in front of such a simple machine . Bravo

I see a great future to it.

Happy Easter at all

Hi all

After playing with the device, i came to a very bad idea.

I mean could this device be OU ?

I have made a drawing (see pix) to explain my thinking.

1 - the height of fall is the same on both power turbine on the bottom of the drawing. So for me the power available with or without the oscillating tubing is the same. But perhaps that could be an avantage on the pulse jet in comparison with the regular jet.?

2- the pulsing movement should not decrease the power of falling water, but it can spin a generator. Is it free energy ?

hmmmm what do you think ?

good luck at all

Irrigation pump

@woopy,
I see you liked this too. Attached below is a quick drawing i did to show my next experiment. The diaphram pump body will be 4" or 6" steel pipe sealed on one end with metal plate and the other with a peice of tire innertube( as diaphram). A rod will connect to the u shape badder to the center of the elestic diaphram and the oscillation will hopefully run the pump. I will be using two 3/4 swing-checkvalves( that is what I have on hand). On the outlet side I am going to start with small tubing(cost), and see how high I can pump uphill. It may take me a couple of weeks to get this going, because I am super busy right now. If any one else wants to give it a try, please post a video of your progress.

Also, I noticed on on woopy's video, I noticed that he had the balloon hooked directly to the water tap. I experimented around and it also works quite well with on open gravity feed( funnel).

I am really overwhelmed I saw your message and Happy Easter to you Laurent also.

You dont know how happy I was, to see someone else try out such things, it was so beautifully made and simpler and to tell frankly the choice of materials used was very good giving a better demonstration than many of my videos and actually I never tried directly connecting balloon to tap and I can see it dancing so elegantly with each oscillations.

I also like the description " Prashants oscillating waterfall", I should have chosen that as the tittle.

I was really disappointed initially especially with people here, their absolute lack of interest except for one professor with whom I got permission to work in lab. Many of them simply don`t have the patience to even look at my complete videos of what i have done. I just cant believe that people do take so much interest and try out and spend so much of their time in building such interesting things.

I really thank all of your guys for showering me with so much encouragement and best wishes.....and to know that so many are interested in my work and actually working on it is real honor to me....

Dear friend,

Another nice innovative drawing I am not that bright to grab everything I see initially but I just have one point from my observations that the jet velocity of pulsatile flow is much less than otherwise if there is no balloon/bladder in between for the water to flow and it offers considerable resistance and some part of it is translated into oscillations.
I dont know the full form of OU..
Below is simple line diagram what i made to make others understand but I know many of them here got the idea..

This is really interesting, I had not seen this before. Would someone be willing to take a stab at the mechanism behind this....We are talking about a passive oscillator with many implications, I get drawn to all innovative forms of passive device, as these show natures path.

Hi all

Good stuff here,
i made a small experiment with a rigid L (inverted ) and low diameter tubing. So the short part of the L goes directly in the balloon, which is directly bounded to the Tap.

I hold the long L part in my finger (no U shape an no gummy ) to get the feeling of the pulse movement.

Than i put one finger to stop the output at the end of the long L tubing , i expected a pressure but it was a strong vacuum on my finger.

I will try to measure the output flux, but as Mr Uday said it seems not to be more powerfull than the regular flux. (perhaps less because charge loss in the different tubing and the ballon ) Have to check it.-

Than i tried to act on the ballon and the frequency of the pulse can be greatly modified. Probably we will have to build a more reliable valve system to get a more regular oscillation.

So this device seems to be highly tunable.

OK everybody let's go and try.

good luck at all

Resonant Effect

I notice the resonance apparently required in this setup. It is physical not electrical but I believe the same principles apply. If you are trying to describe this with a physical formula, I suggest the phenomenon is related to the compressibility of water which is typically assumed to be non-compressible. This is not to minimimize the elasticity of the hose and the spring constants.

[Gdez]

Resonance

@ wayne. I agree with you about the resonance. The cool thing about it is that it seems to self tune itself and by no means did I have a specific plan about bladder size, pipe size, or any type of flow adjustment. That doesn't mean that it can't be tuned in better though. Also, I beleive that much of the effect is just water hammer. Turn a 2 litre bottle and turn it upside down and you will see a similar effect. I have also experienced the power of a huge air bubble shooting up to the top of a 12" chilled water pipe in a 20 story hospital and when it hit the top, it shook the entire building. Check out WATER HAMMER WIKI. I have to deal with the water hammer effect alot in my trade, but it just never occurred to me to try and actually utilize the effect. A hydraulic ram pump works off of water hammer effect also.

The pressure not only at the output but the entire tubing is negative and it fluctuates most widely in sub-atmospheric range at outlet of collapsing bladder. I will show you the pressure tracings which I recorded.
In fact the collapsing bladder acts like a 'Starling Resistor" but in "Starling Resistor" there must be external compressing force, here the normal atmospheric pressure is the compressing force as the pressure inside is sub atmospheric...
Uday

[udayprashant]

The device is very much tunable. Easiest way is to control the input of water into the collapsing balloon by a valve. The other easiest way is to change the height or length of distal tubing attached to collapsing bladder. The frequency and strength of oscillations are function of flow rate, height, diameters of tubes, volume of collapsing bladder and spring constants of supports or springs.
