Hello,
would anyone have a copy of "Elements of Industrial Heat Transfer Predictions" which is the document on which the k-w-SST incompressible turbulence is based. If anyone has a copy I would greatly appreciate getting my hands on one. -Louis |

Hi Niels,
there is more than one paper by Menter on the k-w model; I managed to find a technical paper released by NASA: http://ntrs.nasa.gov/archive/nasa/ca...1993013620.pdf (author is Menter). However, the paper I am looking for is the one cited in the source of the k-w-SST turbulence model. It was apparently published at the 16th Brazilian conference of mechanical engineering and I can't find it anywhere. Have a good day, -Louis |
Hello Louis,

Hello Louis,
I have been searching for this paper as well and couldn't find it. I emailed with dr. Menter and he said: " I am not certain how the proceedings were published. Attached the closest thing I could find." The paper is: "Heat Transfer Predictions based on Two-Equation Turbulence Models with Advanced Wall Treatment" T.Esch and F.R. Menter - Turbulence, Heat and Mass Transfer 4. Ironically the paper you are looking for is also referenced in this paper, and only a brief overview is given. I can send it to you if you email me, same for Niels off course. Email is my_Username_at_hotmail |

The paper exists.
Hi, everybody.
According to the bugs report below, the paer, Elements of Industrial Heat Transfer Prediction, does exist. But we can not read it. http://openfoam.org/mantisbt/print_b...php?bug_id=232 Are there anyone find it helpful to understand the komegasst model in OF after reading that paper, Heat Transfer Predictions based on Two-Equation Turbulence Models with Advanced Wall Treatment? Besides, can anybody send me a copy of Heat Transfer Predictions based on Two-Equation Turbulence Models with Advanced Wall Treatment. Thank you a lot. My email is shawnqin2014 at gmail.com shawn |
These two are available online:

Hello all,
I contacted a number of authors who made reference to the COBEM paper, and found someone who pointed me to what looks to be the complete proceedings from COBEM 2001, available in the public domain no less: http://www.abcm.org.br/pt/wp-content...f/Lectures.pdf Therein is the difficult to find Menter 2001 paper. Hopefully this will make the paper available to one and all, and end the aura of mystery surrounding it! Regards, Daniel |

Menter's 2003 paper is more in line with the OpenFOAM implementation than the 2001 paper that's referenced in the header file (if, for nothing else, the fact that the coefficients are written as 1/sigma, which gives values written in the 2003 paper). http://cfd.mace.manchester.ac.uk/flo...-SST-paper.pdf |
Hello Eric,
Thanks for your response. I am having a hard time finding the alpha = 1/sigma difference in the papers, though; looking at the equations in the two papers, they both have the sigma terms (sigma_omega1, etc) and they are used the same way. I think I found the error in sigma, but it is not in the last term as indicated in the kwSST.H code; rather, it is in the second-to-last term where Menter 2001 gives: But Menter 2003 gives: Which is consistent with OpenFOAM: Code:
alphaOmega(F1)*mut_ + mu() Code:
tmp<volScalarField> alphaOmega(const volScalarField& F1) const Thanks, Daniel |
Dan,
I think the OpenFOAM implementation is very accurate. The coefficients are definitely written as alpha = 1/sigma, but the nomenclature differs from the literature. For instance, if you look at Menter 2001, = 1.176. The reciprocal of this is 0.85034, which is the exact value given to in the code. Now, OpenFOAM writes these as etc, even though Menter keeps the nomenclature in 2003 (even though the 2003 and 2001 coefficients are certainly not the same in face value). Long story short, the coefficients that are in 2003 are in fact what OpenFOAM calls "alpha" in the code, and (sigma being the value of any coefficient from 2001). Naturally, this also means that: Code:
alphaOmega(F1)*mut_ + mu() Hopefully I have answered your questions properly. I have combed through the incompressible portion of the code thoroughly and have read several of Menter's papers. Looking at the compressible code, there doesn't seem to be any fundamental differences. |
Hello Eric,
Thanks for your response. I understand that alpha and sigma are reciprocals, therefore it follows that to remain consistent each instance of sigma in the Menter papers would have to appear as 1/alpha in the OpenFOAM code, would it not? If I look at the code for the turbulent kinetic energy equation, I understand the laplacian term to be implemented as follows: with alpha_k1 = 0.85. The [Menter 2001] paper shows the same term as follows: with sigma_k1 = 1.176. The [Menter 2003] paper shows the same term as follows: with sigma_k1 = 0.85. I am satisfied that the above expressions are equivalent. So if sigma from Menter 2003 is equivalent to alpha in OpenFOAM, which is equivalent to 1/sigma in Menter 2001, then how can it be explained that the equations for CD_kw, F1, as well as the last term in the omega equations, are the same in both papers, even though each contains a sigma term to the same power, but they have reciprocal values? The difference in the omega equation can be explained as an error in the Menter 2001 paper as explained by the OpenFOAM code, but if the equations for CD_kw and F1 are the same in both papers yet the constants are different, I do not see how they can be equivalent. Perhaps there is an inconsistency between the two Menter papers and not with the OF code. Daniel |

I have pondered the same on these two terms before but dropped the issue some time back. It may just be an inconsistency between Menter's papers, as you say, but may be worth a try with reciprocated coefficients. |
Hello Eric,
Thanks for your feedback. I looked through the code with a fine-toothed comb to try to convince myself that it matched one or the other of the references, and found some more differences: F1: - arg1 (OpenFOAM) = min(10, arg1(Menter)); why was this done? - Within arg1, OpenFOAM removed the rho from the numerator and from the CD_kw expression, which is fine if CD_kw < 1e-10; if not, CD_kw = 1e-10 and then the rho does not cancel, making the OF expression = Menter * 1/rho (and therefore a units mismatch). F2: - arg2 (OpenFOAM) = min(100, arg2(Menter)); why was this done? kEqn, omegaEqn: - Not clear what the influence is of the Su term on the LHS - Pk appears to be related to the SuSp and rhoGammaF1*GbyMu or min(G...) terms, but I am not certain. Any ideas why these changes were made to the model? Thanks, Daniel |

I.E., values for F2 very near the wall can get very large, depending on your first cell height (especially thanks to the y^2 value in the denominator). So, adding a ceiling of scalar(100) to this term prevents this (and, I'm assuming, any funny stuff that might happen near the wall when calculating the eddy viscosity). If you can imagine, since nut is calculated as: Code:
nut_ = a1_*k_/max(a1_*omega_, F2()*sqrt(S2)); Code:
max(a1_*omega_, F2()*sqrt(S2)) Quote:

An edit to that post. The tanh makes the large F2 irrelevant, but there is no point in storing so many digits I suppose. Hence the limit.
