چکیده
Purpose of this study is to numerically investigate combustion within a porous channel, which has three layers with different pore densities. Non-premixed inside the channel modelled thermal non-equilibrium energy equations. Flow and chemistry are decoupled tabulated using flamelets, thereby reducing computational cost. GRI 3.0 mechanism used account for methane/air combustion. Simulations performed densities at third layer in 8-30 PPI range. Also, effects power excess-air-ratio (EAR) investigated burner. Temperatures species mass fraction distributions obtained. Maximum temperature burner found be similar all cases since occurs stoichiometric conditions flame front as result non-premixed model. NOx CO emissions values simulations compared against international gas emission standards. This comparison showed that while always below standards, these limits only high excess air ratio power. Besides, density decreased, decrease strongly.

Flamelet Analysis of Turbulent Combustion
Three-dimensional direct numerical simulations are performed of turbulent combustion of initially spherical flame kernels. The chemistry is described by a progress variable which is attached to a flamelet library. The influence of flame stretch and curvature on the local mass burning rate is studied and compared to an analytical model. It is found that there is a good agreement between the simu...

متن کاملA flamelet-based model for supersonic combustion
The renewed interest in high-speed flight has recently demonstrated the need for the development of hypersonic air-breathing propulsion systems, i.e., in which the ambient air is used as oxidizer. These systems have long been recognized as the most well-suited for hypersonic propulsion. Although a traditional ramjet is most appropriate for supersonic speeds (Mach 3 to 5), hypersonic speeds (Mac...
متن کاملA flamelet model for premixed stretched flames
A mass-based stretch rate is introduced. Combining this stretch rate with the conservation equations for premixed flames gives a set of quasi-one-dimensional flamelet equations, which describe the structure and the mass burning rate of these flames. An integral analysis is applied to the flamelet equations and subsequently a general expression for the mass burning rate of stretched flames is de...
