I need some help with CHEMKIN and Phoenics.
Does anyone know if the CHEMKIN interface has been made to work in Cartesian Grid coordinates in the 2009 version of Phoenics?

Thanks.

The VR Editor has not been extended formally so as to facilitate the set up of PHOENICS-CHEMKIN cases, and so care has to be exercised when setting up such cases in the VR Environment.

That still does not answer my question. If I write it in INFORM or thru Q1 modifications does it work with a Cartesian GRID?

As far as I am aware the PHOENICS-CHEMKIN interface (gxchki.for) works in Cartesian Coordinates for all releases of PHOENICS.

Thank you very much. This helps a lot.

can anyone give me some clue on how to work on the software of CHEMKIN?

CHEMKIN in relation to what? You mean CHEMKIN and PHOENICS? See tutorials on CHAM's page. For CHEMKIN by it self, sorry can't help you there.

Hello
I'm a student preparing for master degree in mechanical engineering .
I'm trying to simulate the IC diesel engine combustion by using ANSYS fluent 14.5
i need your help about:
- Reaction kinetic schemes in the chemkin format for n-heptane and how can i integrate it in fluent
I am looking forward to hearing from you

Kind Regards

[quezacolatus]

Hey,

Unfortunately I haven't been working a lot with Fluent so don't know my way around it that much. I can help you with the n-heptane mechanism though, ckm format as well as the transport coefficients and reaction kinetics. You can find them all here https://www-pls.llnl.gov/?url=scienc...tane_version_3

I recommend you do some checking on how to do that. http://www.reactiondesign.com/products/chemkin-cfd/

Hope this helps,

Best,
George

thank george the proble how can i download to fluent
best regard

hello,

I am running diesel engine simulations in fluent by importing reduced nheptane wisconsin mechanism but unfortunately it is not showing combustion . If anybody has done this problem ,Please reply as soon as possible.

Thank you

Hello Guys!

Somebody that has experience with CHEMKIN files, can explain me, how can i put this information in the way of TROE, LOW or SRI for pressure dependent reactions?

The best way to learn how to do this (it's not too hard) is to run through - I think it's library case 644... but you can search. Basically there are two aspects to the CHEMKIN-II facility in PHOENICS - one is the support for multiple species properties and reactions (interphase transfer rates, using the McBride coefficients for species and the L-J potentials for viscosity, etc.). The second aspect is the solver - CHEMKIN-II is a fully implicit solver, so there are both the standard PHOENICS solver (which is SIMPLEST) as well as the CHEMKIN-II point by point solver, available. There is a somewhat difficult-to-understand CHEMKIN tutorial which shows the settings which need to be made in the .q1 file in phoenics input language (PIL).
