Resumen:
Computational Fluid Dynamics (CFD), through high-performance computing and robust codes, has proven to be an invaluable tool for the simulation of combustion processes, ranging from low speed diffusive flames up to detonations. This work intends to provide a review of details needed in modeling as Reynolds-averaged NavierStokes (RANS), large eddy simulation (LES) or Detached eddy simulation (DES) energy equation in CFD codes used for solving chemically reacting turbulent flows. When the density is variable, traditional Reynolds averages introduce many open correlations between any quantity f and density fluctuations ρ0f0 which are difficult to close. Therefore, Favres mass-weighted average technique must be preferred.
