Dear Nidheesh Narayan,

Calculate the velocity perpendicular to the flame surface. That will give you the value of laminar flame speed.

Interesting equation can any an expert prove more information

Please use CANTERA CODE. Excellent code to determine the Reactor dynamics. By the way, determine the velocity contours in your combustion modelling and determine the flame velocity. It is just reading data from the CFD modeled after solved in FLUENT. Read the Contours and check for laminar flame velocity.

I suggest to Use CANTERA CODE. I did it to get the AFT, LFV.

You can refer to works of Nataraja@ iisc bangalore , Yarasu ravendra et al from IISC bangalore for emphirical relations.

Thank you so much... "Sir Syed Mughees Ali " ..

I got up with more better ideas and interest towards this field from your valuable suggestions and feedback. I worked on FGM( flamelet generation manifold) method under partially premixed combustion model.It was very difficult to import the Gas phase chemkin mechanism file for flamelet mixture, have tried several chemkin input files ,but everytime results in an error as "....unexpected word , , in chemkin file, at line. no. 1..." .Chemkin file is based on LPG flamelet. I have attached my chemkin input file and thermodynamic database here...kindly view the attachment and provide suggestions.

Dear Nidheesh Narayan ,

I seems like there is an issue with Thermodynamic data file. Inbox me for details

Ok Sir Syed Mughees Ali . Thanks a lot .....
