EDM constants A and B -- CFD Online Discussion Forums

Radha Raman Das Guest Posts: n/a	Hi, I am modeling for Hydrogen combustion by using the standard Eddy dissipation model. When I used the default values of 4 and -1 for A and B respectively, the maximum flame temperature is 2900 K. To match the experimental data (from a paper that I was referring to) of max temp of 1600 K, I found that A and B should take values of 0.5 and -1.0 respectively. My doubt is whether such a low value of 0.5 for A is acceptable? Is there any lower limit on the value of A as such?Is such a value theoretically valid? Regards, Radha Raman das.
