I had the simulation upon combustion in ANSYS FLUENT. Reaction was based on the "Federick and Dryer" global mechanism. Solution was able to obtain convergence but i need to find the flame speed.kindly give any valuable suggestions.
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.
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.
