Hi, everyone!
I don't know if I post the thread here right or not. But I really need some help about chemkin. I did a 3d simulation using openfoam, and got the T, p, composition at a specific point. now I want to analyze the reaction path using chemkin. however I searched the web and found no info about my question. so, does anyone know how to draw the reaction path using chemkin by giving a specific composition, T, and p? (what I thought is that I have the inp file, I have the compositon and T, so I can calculate the reaction rate at that point, then I can draw the reaction path. but I don't know how to use chemkin to implement this.) thank you for your help! |

Hi mate, i'm on the same problem myself. How did you manage to find the composition at specific points?

Hi,
do you mean to find the composition in openfoam? if so, you can use the probes function of openfoam to monitor the composition in runtime, like this: Code:
fieldProbe { functionObjectLibs ("libsampling.so"); type probes; writeControl timeStep; writeInterval 100; enabled true; probeLocations ( ( 0 0 0.34) ( 0 0.013 0.34) ( 0 -0.013 0.34) ( 0.013 0 0.34) (-0.013 0 0.34) (0 0 1.77) ); fields ( T U X_CH4 X_CO2 X_H2 X_H2O X_N2 X_CO p ); } then you can get all the information like point coordinates, temperature, composition, and so on. |
