| 内容記述 | In the present paper, an analysis is made on the problem of ignition and flame stabilization of the steady stream of combustible gaseous mixtures in the laminar boundary layer on a porous flat plate, from the surface of which hot inert gases or combustion products are injected into the boundary layer, and the effect of hot gas injection on ignition and flame stabilization in the boundary layer is examined. A one-step unopposed global reaction following any order reaction kinetics with temperature dependence according to the Arrhenius rate law is assumed. The boundary layer equations of aerothermochemistry are solved for the special case where ν_ω(χ)∝√<μ∞/χ> by the iterative method and the general analytic solutions of N'th approximation to the temperature and concentration profiles across the boundary layer are presented. These analytic results are then applied to the problem of the thermal decomposition of azomethane and numerical calculations are carried out for the first-order approximation. It is found that the effects of hot gas injection on the ignition and flame stabilization in the boundary layer are remarkable and the characteristic stay time decreases monotonously with the increase of injection rate. This is due to the fact that the temperature profile in the case without chemical reaction (i.e.x=0) approaches the separation-type profile as the injection rate increases. | |||||||
