| Resumo | We analyse premixed ames inside a narrow channel.This topic matters the most when it comes to security and propulsion. It's study started in order to analyze ames propagating in coal mines, contributing later on to chemical industries. Intrinsically, the problem is two-dimensional, but applying weight mean procedure, it is possible to describe the problem with 1D conservation equations making usage of convective heat transfer model. Considering the gas and solid phase conjugated problem, the system is adiabatic, then all heat transferred from the ame to the tube walls returns to the fuel mixture. As in most cases the heat conductivity in the solid phase is much faster than that in the gas phase, problem's description requires two main thermal zones with very dierent length scales. The largest scaled one is associated to solid phase conduction, while the smallest reefers to the gas phase. The analysis focused in showing the in uence of these two thermal zones, once their dierences contribute to the understanding of the propagation of heat on the channel wall and on the ame. Similar studies on this, however treated in porous media, show that the ame temperature will probably rise above the adiabatic values. Solving the particular equations of mass, energy and species conservation, it is used the method of singular perturbations (asymptotic expansion), mating outcomes for dierent regions. The perturbation theory provides solutions as series expansions having as parameter the ratio between the thermal conductivities of the solid and gas phases. Other parameters in the mathematical formulation are oxygen and fuel's Lewis numbers and also the convective heat transfer parameter. For conditions in which the convective heat transfer parameter is close to unit, the two phases are not in thermal equilibrium, so the heat circulation between phases happens largely and the ame temperature can reach up to twice the adiabatic temperature (theoretically estimated value). Further, a third region is analyzed along this work. It has a heat-reactive character and its length scale is appropriate to describe the ame inner structure. The inner region study coupled with the outer region one solves the problem. | |||
