Here's the continuation.What else struck me in these articles was these three-dimensional diagrams built using these formulas. [Full image copy of journal article deleted by the Mentors to avoid copyright violation]

If you are interested in what a turbine operating on this principle looks like, here is one of the possible options. This is a small prototype

I gave you an example from Wikipedia (just like you).If you look at other languages, you will see the same thing. https://de.wikipedia.org/wiki/Froude-Zahl https://es.wikipedia.org/wiki/N%C3%BAmero_de_Froude...

They use a Gorlov helical turbine.It is considered most effective in free flows, due to the extraction of kinetic energy.

Thank you. No, I won't do that. If the material seems uninteresting, then I don’t mind it not being discussed. But, it seems to me that even unpublished material is discussed here, which does not contain any scientific content at all, for example Small-scale hydropower generators installed in...

I also wondered about this question and realized that the Froude number is written slightly differently in different sources. Here is an example pl.wikipedia.org Froude number But as I understand it, since this is a dimensionless coefficient, it is not its absolute value that is important, but...

Agree. Therefore, I believe that a differentiated approach is needed here. Otherwise, the forum runs the risk of refusing to discuss interesting ideas (even if they have not yet been published anywhere). Or, for example, they are published in another language. After all, science develops not...

And I just gave examples of “unrespected” publications in which the works of Carnot and Mendel were published. Does this make their ideas unnecessary and unimportant? Have you read the excerpt from the article in arXiv? If you didn’t have any questions about it, then you shouldn’t have any when...

Strange. Is Russian science somehow different from generally accepted science? What if some interesting articles were published there? Do you remember why the ideas of Carnot or Mendel were not implemented for a long time? Because they were published in unimportant publications. This slowed...

Excellent, thank you. To begin with, there was an excerpt from an article in arXiv in Serbian, automatically translated into English. If there are no questions about it and the equations that are derived there, then I will post the article preceding this one. Please. [Full image copy of...

No, this is not my research. And I thought this would be a good place to discuss them here. As far as I understand all the publications and designs of different people. But everything is interconnected. My attention was attracted by the unusual physical and hydrodynamic calculations, the...

I wanted to discuss the unusual design of a high-power hydraulic turbine. I'll start with this excerpt from the article. The article is in Serbian, so only an autotranslation. Has anyone seen formula #6 in any hydrodynamics textbooks? [Full image copy of journal article deleted by the Mentors...
