چکیده
|
In turbulent combustion flows there is two phenomena namely turbulence and combustion. these two phenomena interact mutually. the turbulence causes fluctuations of all variables,however the combustion acts on the density and viscosity. in this paper we are interested in the study of the influence of the turbulence modeling on the characteristics of methane diffusion flame behind a bluff body obstacle,using the assumed probability density function with beta function for the estimation of the temperature and the mass fractions of species. the beta function parameters are the first and second moment of inert scalar.
