strain rate and scalar dissipation
Dear users,
I am simulating a swirl flame using non-premixed flamelet model. The fuel is methane. I create a flamelet by importing mechanism and thermodynamic database file (GRI mech 2.11 mechanism). I am referring a journal paper where they have a simulated identical flame. The have generated a single flamelet using strain rate of 500/s. I create multiple flamelets using very low initial scalar dissipation and allow flamelet to extinguish. My mixture fraction profile is not matching with experimental results. Hence i want to see the effect by generating single flamelet. How do I create a single flamelet using the given strain rate of 500/s.?? (is strain rate same as initial scalar dissipation)
