Hi All,

Can anyone suggest me some books about how BFC grid works? I have read Malalasekara: An introduction to CFD. It was good for basics, but no detailes about BFC.

Do you mean Boundary Fitted Coordinate grids? If so, try Thompson´s classic book "Numerical Grid Generation: Foundations and Applications". You can download a free copy from the Mississipi State University website (http://WWW.ERC.MsState.Edu/publications/).

If I recall correctly, you guys use PHOENICS at FETI. The appropriate link, therefore, would be:

Go to the PHOENICS Forum to request more information.

Thank you very much! "Numerical Grid Generation: Foundations and Applications" is exactly what I was searching for.

Thank You! I have already read it. I am planning to simulate optical fiber drawing for my PhD thesis. I am looking for the best way to simulate radiative heat transfer. I would like to implement DOM or Finite volume (control angle) to PHOENICS. Has anybody tried it yet?

Gyorgy

Hi Gyorgy,

We (at the Solar Facilities Research Unit, Weizmann Inst. of Science, Israel) had implemented a control angle RTE solver coupling to PHOENICS for simulation of volumetric solar receivers.

Rami

Hi Rami, Cartesian or BFC grid did you use? In your opinion what is the best way to handle control angle overlap?

Gyorgy

Hi Gyorgy,

o We use BFC grid. o We treat control angle overlap by the so-called "pixelation method". I can't claim it is "best", but it makes sense theoretically and it works fine.

Hi Rami, Can you suggest me some papers about "pixelation method"

Thanks,

Gyorgy

The original paper is J.Y. Murthy and S.R. Mathur, "Finite VolumeMethod for Radiation Heat Transfer Using Unstructured Meshes", J. Thermophys. Heat Transfer, V12 N3, pp. 313-321, 1998.

Thank you!

It is a very useful article.
