global or detailed reaction mechanism

    • micro

      hello everyone

      i am trying to study H2-O2 combustion in a micro combustor with a 9 species 19 reactions mechanism using Fluent

      plz refer to the file attached

      doing the simulation with global reaction was giving outerwall temp of around 1300K but with this mechanism its reaching only 900 K

      plz let me know do the values of the constants ie...activation energy etc have to be given as such as is given in this mechanism or do i need to do some conversion

      also what could be the cause for this temp dip

      i have k-epsilon turbulence model and eddy dissipation concept
