Modelling Combustion in Porous Zone
I am having problems in defining combustion in porous zone and will appreciate any inputs.
I am a student in Malaysia, currently working on a design project. I am assigned in building a simulation model of porous burner. It will consist of a mass flow inlet, which it will enter a porous zone where combustion is ignited. After the porous zone, the temperature will be observed. They are defined into three fluid zone, 'before porous', 'porous zone' and 'after porous'.
Being a beginner in FLUENT and CFD, I find this tough and challenging at the same time as I need to learn two new things - defining porous zone and using a combustion model. BTW, I touched a little bit of CHEMKIN and thus have ideas of the mechanism files etc.
After some studies, I manage to define my porous zone correctly (as I see velocity slowing down) and I found the necessary equations to define the inertial and viscous losses, yet to compute the value I need though.
However, I am having issues with defining the combustion and FLUENT user guide does not help beyond my problem.
I intend to use the pre-mixed combustion model but will take advice on choosing the partially pre-mixed model if necessary.
My problem is that:
Do I miss out anything important? I was reading FLUENT user guide and saw reaction could be defined in porous zone. I think I overlooked it in FLUENT or it isn't there for me to choose from the beginning.
I am away from my university currently and will only be able to access FLUENT by Monday. But certainly, I wish to collect as many ways of doing it as possible now so that I can run it when I reach my university on Monday.
Kindly direct me to any literature that you think might help me. Even if I can't access it from my home, I could grab and read it when I reach my university.
I facing problem in modelling and simulating premixed porous media combustion in fluent/CFx... It would be really helpful if someone can someone share the procedure to be done for simulation
Modeling of porous surface burners with Fluent (premixed)
I am experiencing problems when modeling porous surface burners too. I would like to model a porous surface model with a premixed methane/air mixture, using a detailed mechanism in order to determine the NOx formation. However, I am experiencing many convergence issues.
Weere you able to find a solution for your premixed porous media?
Thanks a lot for your help,
