can some one tell me how to set initial scalar dissipation in non-premixed combustion, steady flamelet. How could i know what is the value of my scalar dissipation? may i read it from previous non-premixed combustion calculation? and if not, how to calculate?And what is the proper value for maximum number of flamelet and scalar dissipation step?
