Turbulence in the Pantone reactor?

[lio74]

Hello, what you say is interesting:

with Ansys can you do flow simulation?

I am an automotive engineer and I would like to see what it gives for the flow in the Pantone.
...

hello bob!
yes Ansys does flow simulations, thermo, and structural sizing of course ... and other stuff too.
at the same time you may never have seen it because you don't have the fluids mechanics module!
there is other thing also like FLUENT or ABAQUS .... the software is not what is missing ... on the other hand the licenses !!! $$ €€
on Ansys dit FRANSYS chez nous look in the preference menu (before preprocessor ...) choose "FLOTRAN". Tomorrow I send you an MP from the university ...

As for turbulence they are essential for me (increase in electrification by flow)

so you are of the same opinion as me: it has to swirl a max !!!

otherwise i am on forum recently and I see that there are very good handymen and thinking heads
we have not yet saved the world, but we are deeply involved ...
@ + the savings

Why not give it a try?

[lio74]

hmmm
well i had an idea in style ... a filtered rod for the reactor rod
not to the left because the stem is oriented from south to north ... then there is a rotating field ... heuuuu ... otherwise c in the other direction Finally it must be in a good way

for the turbulator would still need a sacred wick d = 20mm ?? !!

Has the threaded rod been tried by andré to no avail, unless there is a difference in changing the pitch?
For the wick it is depending on the reactor and the iron between you want, the problem would lie rather to center it, there is another pair of handles!
As a turbulator you also have balls that would not hurt.

Hi everybody

One of the reasons why André did not feel any improvement
with the turbulence generator or the drill bits
may be there geometry of its pipes:

He explained in a post that he had square section pipes upstream of the pantone.

These angular shapes alone can create turbulence, just as if you have an elbow just before the pantone.

Following an internship on the pantone, the guy explained that it was useful to put a small bar across the pipe just before the reactor.

it would confirm the need for turbulence for proper functioning ...

[paotop]

... that's why I launched this post because I found that a "spad" type mounting was anything but aerodynamic and yet had a high yield compared to more careful mounting ...

[lau]

And yes bob, the rod centralizers also make a turbulance.
I'm going to remove my elbow that I had intentionally put on the steam heater to try this wick story.
I'm still really skeptical, there are so many parameters that come into play like the ideal radius of curvature of the vortex depending on the diameter of the rod and the speed of the flow, to take just this example.

Has the threaded rod been tried by andré to no avail, unless there is a difference in changing the pitch?

well yes, we have to find out which way it turns (there chui not very sure of me)
IN WHAT SENSE do the particles rotate in the reactor ???
finally, the purpose of putting a threaded rod is to increase the contact surface between the fluid and the reactor rod. So if we take a very large step (and in the right direction so as not to upset the mess ...) we can (maybe) simply have the same rod and tube diameter of the reactor => the gas will pass only through the threading !! but beware of pressure drops ....
if not in the same register: someone tried to put a spring around the reactor rod ???

otherwise bob, did you find the checkbox in Ansys ???
I no longer find the trick to put an attached file ... so I can't show you the imprecran !!!

I don't have Ansys, look at the Private Message I sent you.

:-(

I too am skeptical about this story of calculating threads, and at least as much about the meaning of threads.

What is necessary is that it brews, that it stirs, it is necessary to break the linearity, without however making too great a pressure drop.

The mere presence of an elbow at the entrance of the pantone disturbs the linearity of the flow. As the roughness of the rod and the reactor will increase the electric charge of the gas

(according to the theory of electrification by flow which I support with all my heart and my reason:

well dsl but that put me MP [0] then I had not seen it!

clear to circulate the gas in the thread is a ridiculous idea ...

but if not a spring ... even an electrified spring?
another crazy idea you tell me !!! when I have the opportunity I will test all or almost all my ideas of young crazy, you never know there may be one of good in the lot !!

good I stop too bubbly siboulo ... I already take care of this little simulation on "FRANSYS". color images soon!

thank you for the paving stone to read I put it on my bedside to sleep, it's holy as a sleeping pill

ps: for the free software of mécaflux I inquire.

re,
hi paotop, excuse me for being a novice, the spad is the all-round pantone for tractors !?
it is true that I did not lean too much on the system! what changes a lot compared to pantone ??
