Hello

PS: I see that Andre did not answer for the centering of the rod ... it is that I already had the answer therefore ... centering by welding is not top

Very small welding points are difficult to achieve, even with TIG, already the passage around the rod is restrictive in our assemblies, so 6 large points is almost 50% less.
As a starter it would still be (tolerable) but in the end the rod not acceptable.
A very narrow welding point at the entry of the rod favors the vortex which makes the spiral, (or an entry at 90 degrees) yet I have not succeeded has proved the usefulness of the spiral, nor of the magnetism of the rod, these things are visible, but what is it for? , the only thing that interests me is that it works as well as possible ...

Often in my small assembly the rod does not include any centering system it is simply put in the reactor just a small rod forward to prevent it from being sucked like a piston, it works as well.
In an idling car, it makes the noise of a pan in slow motion and attracts attention in town at traffic lights.

Hello !

Thank you for the details

Very small welding points are difficult to achieve, even with TIG,

well on the assemblies of last week we made patés with the arc, then grind with the disc grinder to shape the points and make a more conical shape ...

As a starter it would still be (tolerable) but in the end the rod not acceptable.

OK OK ... so the next assembly we will do a centering of the inlet weld point and threaded rod in the outlet elbow of the reactor
it will avoid "gling gling" =>

In an idling car, it makes the noise of a pan in slow motion and attracts attention in town at traffic lights.

Good start to the week, everyone

Bonsoir

With my assembly, I have no centering problem, I may have others (flow restriction).

I made a new venturi, according to the advice of the subject "Ideal Venturi", I would put the photos on this subject.
Beautiful realization your venturi.

Mine is in PVC tube heated with a gun and formed with the bottle and a weakly conical mandrel.

Compared to the previous version it works (too) well.
I doubled my water consumption (2l / 100) and lost the benefit of pantone.

So I reduced the flow. By lowering the tank, but I'm almost at the mini and that was not enough.
So I put some stainless steel scouring straw back into the main outlet tube. The water consumption has returned to approximately 1l / 100.

Yesterday I bought and installed a double K probe thermometer. (Thanks Camel1 for the info)
1 at the main outlet.
1 in Pantone output.

My first readings are:

GV without straw 80 ° maxi at 130Km / h
Main with straw 108 ° to 130

Pantone without straw 74 ° maxi
Pantone with straw 89 ° maxi

Do these values ​​(Pantone especially) appear to you to be within the "standards"

I specify that my probes are on the periphery of the tubes, and that nothing is thermally insulated in my assembly.

I take this opportunity to testify that the GVI is really "reagent".
Example: 200 meters of acceleration is enough to go from 47 ° to more than 80 °

Hi Didier!

So I put some stainless steel scouring straw back into the main outlet tube. The water consumption has returned to approximately 1l / 100.

Yesterday I bought and installed a double K probe thermometer. (Thanks Camel1 for the info)
1 at the main outlet.
1 in Pantone output.

My first readings are:

GV without straw 80 ° maxi at 130Km / h

Pantone without straw 74 ° maxi
Pantone with straw 89 ° maxi

Do these values ​​(Pantone especially) appear to you to be within the "standards"

You arrive at the same observations as me, namely that depression has an influence on the operating point of the GV.
I think you must have missed this:

https://www.econologie.com/forums/mise-a-jour-importante-pour-le-gv-t3768.html

With this mod, you shouldn't have to use the straw, and you could more easily set your level. And set your maximum water consumption independently, thanks to the flow regulator ...
For your T ° value , it fits in the mesh.
Your figures allow you to note the influence on the depression that the straw brings.
Its presence must cushion the variations depression (aspiration is not constant, what we measure with our depressureters, whatever they are, it's an average ...)
In gas dynamics, it must take on a role similar to an RLC cell (appliances will understand!) Which, depending on the frequency of the current, will or will not obstruct its propagation ... The mainsail does not see more or less than the average depression , and it calms the game!

With the modification, the steam generator becomes stable, I think that it is an important stage in the completion of the control of the production of steam according to the engine conditions.
Thanks to this, we will finally be able to do what André - among others - has dreamed of for a long time, is to master all the parameters of steam production in terms of:

- depression range
- maximum temperature wanted (adjustable by dimensions)
- maximum water flow rate (adjustable by dropper

It will become possible to explore the terra incognita of optimizing the quality of the steam and its quantity, because if the "bad" steam has a negative influence on the performance, what becomes of it if we send which "good" vapor?

It's going to be exciting!

I specify that my probes are on the periphery of the tubes, and that nothing is thermally insulated in my assembly.

Ouch! I think I'll do a topic on it. if we want to be precise, we must take the T ° inside, in the atmosphere, and without influence from the outside or the tube!
Well, I know what it's like to want to try it right away, when you have the toy in your hands

In the process, I did the subject, a little edit and hop, here is the link:

I take this opportunity to testify that the GVI is really "reagent".
Example: 200 meters of acceleration is enough to go from 47 ° to more than 80 ° Didier

Did you see it? a thermometer, to see the beast at work!
Otherwise, I confirm for the "reactivity", about which I speak for a long time on my site ...
Experiment with leaving the steering wheel to someone else, to be able to appreciate the variations of the mainsail according to the engine calls ... You will realize that the slightest slight acceleration will make the T ° move almost instantly. ..


In any case, thank you for your feedback, it will allow us to refine the calculation of dimensions ... for future GVs.

In this regard, in view of little feedback that I have to date from the many experimenters who have contacted me, I think I will write a subject specially dedicated to this subject, intended to collect structured feedback from each other .

Go, to ++, and sorry for the length of my intervention.

Hello

Pantone without straw 74 ° maxi
Pantone with straw 89 ° maxi

If we want to make temperature comparisons on the panton or other outlet, we must really measure the internal temperature of the gases circulating in the tube, there is a big difference with that measured on the duct which undergoes external fluctuations, especially on a duct of copper.

RTD measurements for low temperatures are easier than Thermocouple type K measurements unless you have the proper cold joint temperature compensation equipment on the instrument.
measuring a temperature of 100c with a cold seal at 30c may cause a good error, measuring an exhaust at 650c with a cold seal of 30c the margin of error is more tolerable

In any case, check the instruments in boiling water to make sure of errors.
Currently I use a cooking thermometer from IKÉA maximum 130c, the probe is introduced a 3 cmm inside the duct to minimize the error .. it is close to the outlet in the engine intake, the copper is thermally insulated
