How to generate the TLF and TKI file of ECFM3Z

baibai1995 · July 10, 2021, 05:13

In ECFM3Z combustion modes, we need imput TLF and TKI.
I use 'chemistry workspace' to generatre it. I would set diesel and CH4 as fuel. what's more, the NC7H16 and C7H8 was suggested as diesel surrogate. the 'table setup' of fuel was sat as below:

species 1 2
NC7H16 0.85 0.00
C7H8 0.15 0.00
CH4 0.00 1.0

however, the error " Multi-fuel table does not support more than 2 fuel components " .
what should i do to set multi-surrogate fuel and Multi-fuel in TKI generate model

Hi Yuanqi,

The functionality has been added in v3.0.22. Using multi-surrogate fuel and Multi-fuel TKI and TLF with ECFM in 3D is complicated. It involves creating tabular_therm.dat and more procedures.

Could you please send the request (with description and case setup) to your contact of Convergent Science?
