I want to simulate coal combustion simulation in a furnace.
So, I decided to use coalChemistryFoam.
Before I simulate real furnace, I tested some cases.
coalChemistryFoam tutorial just contains closed chamber case.
My combustion furnace has 1 inlet & 1 outlet. (Simple geometry - cylinder)
I made furnace mesh file by star-CD ver.4
There are 2-type of mesh.
1. tetrahedral ~ 30,000 cells
2. polyhedral ~ 10,000 cells
However, OpenFOAM(coalChemistryFoam) does not work for this mesh!!
(I mean "janaf-thermo error")
checkMesh utility says "mesh is ok"
my boundary conditions like this ( Attachment )
For Hexahedral mesh, coalChemistryFoam is always OK.........
HOW CAN I USE coalChemistryFoam in tetrahedral or polyhedral mesh......
I've never used coalChemistryFoam, but you should maybe have a look at your pressure boundary conditions. Typically you can start with putting a fixed pressure at the outlet and zero gradient on walls and inlets.
I am using coalChemistryFoam too,and I have two inlets/one outlet,and I met the problem of "attempt to use janafThermo<equationOfState> out of temperature range...",have you ever encounter with it?
Usually, this error occurs when low temperatures (below room temperature) occur in the solver. The solver can't look up properties and throws an error.
Injection In coalChemistryFoam
I am working with coalChemistryFoam with an IFRF furnace with 2 inlet and 1 outlet. I disabled limestonParcels because I dont have it in my case. In "coalCloud1Properties" in folder "constant" which is main file in adjustment of coal injection, I chose patchFlowRateInjection for injectionModels, but I didn't find any tutorial that use this injectionModel. In this model we have some cases:
type patchFlowRateInjection;Is this cases sufficient for patchFlowRateInjection?
Why particles didn't come in?
Cloud: coalCloud1JANAFTHERMO errors without entering any particle occurs,why? I have changed kinetic, deltaT but yet there is janafThermo error and no entrance of particles. :confused:
