Numerical Study of Oxygen Dilution and Temperature Distribution of Biogas Combustion in Bluff-Body MILD Burner

Cleaner and more efficient combustion processes are demanded by the combustion industry due to fuel depletion and air quality issues. A numerical study of a laboratory scale combustor is reported. The numerical simulations were carried out using ANSYS Fluent 14.5. Turbulence was modelled using the r...
