Dear foamers

I would like to have a swirl as inlet condition for a single phase flow, preferably when using simpleFoam. I can only find engineSwirl, and no proper documentation - it there any other way to get this property to an inlet BC?

Attached is a swirl inlet velocity boundary condition that I have kicking around. Unfortunately I don't actually know in what condition it is (I haven't needed it for several years), but you might give it a try anyhow.

I would also suggest the lecture of the excellent wiki page of the Sig Turbomachinery at the following link:

http://www.openfoamwiki.net/index.ph...Turbomachinery

Following the link to the Validation test cases you will find explanation about an alternative way to set swirling boundary conditions.

Hope this help.

Thanks francescomarra, have you tried this one on OF 1.6(.x) ?

I was able to compile and use the addSwirlAndRotation utility. It is simple and almost self explaining. It uses the constant/swirlAndRotationDict to define the angular velocity of swirl and the rotation vector.
After having defined the normal component of inlet velocity and interior initial velocity in the file 0/U , by running this utility you get the same file modified to take into account the swirling applied to the boundary and, if desired, to the initial conditions.

It was easy to modify this routine to get different swirling velocities for two coaxial annular jets.

Let me know if you need further details.

Regards,
Franco

Ok. Upon compiling, I get the error " cannot find -lincompressibleTurbulenceModels", also when doing a "full" build of the OSIG-dir.

Did you compile only the preProcessing-directory, or the entire OSIG-package found in the 'Breeder' directory in the SVN?

Problem solved using what's found in trunk 'Breeder_1.5', not just 'Breeder'.

Hey foamers,

i am quiet new to OF and get in trouble by compiling addSwirlAndRotation following the wiki (http://openfoamwiki.net/index.php/Si...diffuser#Case1).
I am using Ubuntu and OF 1.6.x.
First i thought it depends on compiling under OF 1.6.x, but after using google i found this thread.
Can anyone maybe help me al little to fix the errors i get.

By typing:
stonehope@ubuntu:~/OpenFOAM/stonehope-1.6.x/applications_SIGturbo/utilities/preProcessing/addSwirlAndRotation$ wmake

I get the response:

I just got the files from:

svn checkout http://openfoam-extend.svn.sourcefor...y/applications applications_SIGturbo

and

svn checkout http://openfoam-extend.svn.sourcefor...oMachinery/src src_SIGturbo


that means the ../Breeder1_5/..-directories as mentioned above.

I am happy for any request(s).

Thanks.

You just need the application dir in postProcessing called 'addSwirlAndRotation'. Make a svn checkout, and do "wmake", that's it.

And make sure you do this inside the OpenFOAM environment. I put this in an application folder under my "<user>-1.6.x" ...

hey kjetil,

greateful thanks for your quick help!!!

I tried as you told me, but finally it did not start working.

Searching for possible Reasons guided me to the problem with geometricOneField.H .

It is discussed at

OF 1.6.x pulled at 03/05/2009 compilation error

and updating the corresponden link(s) solved my problem.

Compiling is no Problem anymore.

Thx.

Dear foamers,

I really enjoyed your forum discussion about addSwirlAndRotation. Actually, I've compiled addSwirlAndRotation successfully, but it doesn't make any "swirlAndRotationProperties" dictionary file. So, I was just wondering if you could please provide me with a sample of "swirlAndRotationProperties" dictionary file or show me a link of download.

I look forward to hearing from you.

Thanks a lot,
Sina

Hi,

when you take a look to:

http://openfoamwiki.net/index.php/Si...se0:_Base_case

Here you can find something like this:

"....In the swirlAndRotationProperties dictionary you also specify the swirl/rotation in terms of the omega[radians per second] vector and the center of rotation vector. The switches modifyBoundaries and modifyInterior can be modified to control if both the boundaries and the interior should be modified, or only one of them.
An example of the swirlAndRotationProperties dictionary can be found in Case1."


According to this you can find the swirlAndRotationProperties under:

https://openfoam-extend.svn.sourcefo...tionProperties


What you see then should look like this:

// ************************************************** *********************** //



Use this to set your own rotating swirl.

PS: Don't forget to update the BC's for the use of addSwirlAndRotation.

Hi, is this working with compressible flow?
I tried sonicFoam and rhoPisoFoam, none of them give reasonable results.

any suggestion?

Thanks,

Yu

The rotating inlet is changing your inlet velocity field only, shouldn't be any further problem with the solver itself.

Hi, Kjetil,

you are right, the solver is ok.

The problem i think is because paraview did not show correct results. See the attached pictures (Case1.3 from http://openfoamwiki.net/index.php/Si...nical_diffuser).

I plotted the z componet of vector U (U Z) and Uz calcualted from foamCalc (sliced by the plane in the z direction and passing point(0,0,0)). They are different. I checked U file and know the file is ok. I think there is something wrong with paraview.

Thanks,
yu

Hi,

This is my first post. I've problem with paraview or another. In my case (simple cylinder) I've swirl on face "inlet". Swirl is forced by utility named "applications_SIGturbo". My mesh is made in enGrid and it has boundary layer on cylindrical wall. Inlet velocity is 1 (one) m/s. I use simpleFoam (openFoam) to solve it. Problem is, when i start paraview (paraFoam 4.0) the velocity has very very big value (over 1000 m/s !!!) but behavior of a swirl is properly. Does anyone know what is wrong?

thanks for help.
