Hello All,

When I try transplant flameletFOAM to OpenFOAM 5.0, I met the following about YSLFModel.C:

+++++++++++
YSLFModel/YSLFModels.C:41:1: required from here
/home/users/OpenFOAM/OpenFOAM-5.0/src/OpenFOAM/lnInclude/runTimeSelectionTables.H:72:64: error: invalid new-expression of abstract class type 'Foam::combustionModels::YSLFModel<Foam::combustio nModels::rhoThermoCombustion>'
return autoPtr<baseType>(new baseType##Type parList);
+++++++++++

Anybody also has the same issue?

Thanks.

Hi Adlak
did you change the flameletFoam to use the code with progress variable?

Dear author, thanks for the solver flameletFoam. I would like to know "how energy is being conserved" since, there is no EEqn.H in solver. I found there is table called " he_table" in the constant folder. Is this the sensible enthalpy which is defined under thermophysical model and supplying it using table, and remaining thermodynamical properties are being calculated ? I would be appreciated for your comment on it.

Thanks

Hello, Thank you for making such a strong solver and sharing it with everyone Dr.Muller, i am trying to install flameletFoam2.3.x in ubuntu 18.04, i have installed version 2.3.x openFoam and it works properly. my Problem is in making the flameletFoam, every part make without problem except canteraToFoam utility, the error which its given me is this:

Make/linux64GccDPOpt/canteraScanner.o:(.data.rel.ro._ZTV11xxFlexLexer[_ZTV11xxFlexLexer]+0x68): undefined reference to `xxFlexLexer::yywrap()'

Hello, Mohammad
It's been a few months since you posted, I dont know whether you solved it. Here is a solution.
This problem may be caused by flex version check. Solution is modify the canteraScanner.L file(located at flameletFoam/applications/utilities/preProcessing/canteraToFoam), change the line 43

#if YY_FLEX_SUBMINOR_VERSION < 34

to:

#if YY_FLEX_SUBMINOR_VERSION < 34 && YY_FLEX_MINOR_VERSION < 6

As I looked through the forum (and google), there are currently two versions of flamelet models in OpenFOAM--The libOpenSMOKE from Cuoci and Tobi, and flameletFoam from Muller. Does anybody happen to know the differences between the base solvers that these solvers are derived from? The libOpenSMOKE seems to be derived from rhoPimpleFoam and the flameletFoam is derived from rhoReactingFoam from its description. Their pressure equations seem to be very different! What's interesting is, starting from OpenFOAM-5.x, the rhoReactingFoam solver is using the same pressure equation as that in the rhoPimpleFoam solver. But in previous versions, which are the versions that the two flamelet solvers were developed, they are different.

Thanks,
Ruiyan

Dear all

Thanks for the model first! i've tested the sandia flame successfully!

now, i want to calculate the bluff body burner using your model. so,first of all, i need to create a library for the reactants, which is half CH4 and half H2 mixture for the fuel. and the stoichiometric mixture fraction Zst is 0.05. i have set these in the input text.

Then actually, we don't have any initial solutions for this case right? So,i should choose 0 for first choice and then it asked me the equivalence ratio(0-1),which i am not sure about it.

Furthermore, they let me choose the fuel from CH4 and H2(which i found in the flamelet.cpp file,they don't exist such composition,so i add such composition in it,but it still didn't work.) Then i realized it's just for the initial solution,if there is a mixture of fuel then just take one of them for the choice right? So i try to just set CH4 or H2 for the fuel choice, but both didn't reach a convergence even i try to reduce the mass flow in the input file.

So, i just wonder if anybody could give me some hints on how to solve it? lot thanks in advance!

Thanks everyone on the thread for the help in compiling the flameletFoam and special thanks to Hagen Müller for providing the solver.


though I could compile this code with of-2.3.1, while trying to run the tutorial provided I am facing an error (when running canteraToFoam utility after blockMesh). Mesh was successfully generated with blockMesh.



the error read as:

Anyone knows how to solve this problem? I encountered the same problem.

[ShaneheSSSS]

have you implement the export command?

hello，everybody

I‘m recently working on the flameletFoam modification (methods proposed by

Oevermann) for supersonic combustion, and I'm failed. Is there anyone have

the experience?

[niyas]

Dear all,


Recently I started reading about flameletFoam and tried it. It works great..!!


I was wondering, if there is any real-gas flamelet solver readily available ?



Or what would be the best way to develop one ?



Thank you all.....

[dlahaye]

Does this help?

[niyas]

Hi Domenico,
Thanks for your reply.

FGMFoam is also based on ideal gas Equation of State (EOS).
But I am trying to develop a real-gas EOS based Flamelet solver in OpenFoam.

If you find any materials related to real-gas based flamelet model in the future.
Please share..!!

Thanks again..!!!!

hello dlahaye,

Do you know how to calculate the heat release due to combustion in the enthalpy equation under flamelet supersonic modification? namely, reaction->Sh() in openfoam 2.3.0? I tried the flamemaster, which could generate heat release along with the mixture fraction, temperature and so on. But I am not sure it's right, because I do not succeed in modifying.

Thanks!

[niyas]

Hello Foamers,

Has anybody tried FGMFoam ?

I tried FGMFoam and it works well. I have also tried FlameletFoam.

My question is what is the main difference between the two ?

I can understand a little bit but still need an expert answer on this.

[danhnam]

I am using flameletFoam-2.3.0 to reproduce Sandia flame D simulation.
But I can not reproduce the result as Mueller (Author of this flameletFoam) showed in his paper (H. Mueller, F. Ferraro, M. Pfitzner, 8th international OpenFOAM workshop, Jeju, Korea, June 11-14, 2013). The mesh dependency was not a reason (I have tested with refine mesh).

I attach my test case file and some figures here to show the comparison between my results among experimental data, Mueller’s work (8th OFWS 2013), and data of reactingFoam with EDC combustion model (in OpenFOAM-6).

Notice that in this test case I did not use the configuration of computational domain as same as the test case provided for reactingFoam tutorial with Sandia flame D in OpenFoam-6 because I did try but I the simulation looks weird.

Is there anyone, who experienced to reproduce Sandia flame D using this version of flameletFoam, tell me what wrong with the configuration, initial and boundary conditions that I used in this simulation?

Thank you in advance.

Did you solve this issue?. I am getting the same error.
