| 英文摘要 | In this analysis we have studied the Lewis number effects and the kinetics of the reaction in the ignition, extinction and combustion of the monopropellant droplets. We have limited the analysis for the condition of ignition in the cases that, when it occurs, there is an exterior region, in chemical equilibrium, and an interior region, in frozen condition, separated by a thin reaction zone. To describe the process of vaporization with combustion, for large activation energies, we have formulated the problem to find the value of the Damköhler number that corresponds to the value λ for the vaporization rate, when the heat flux at the surface of the droplet is known. To obtain the results we needed to calculate for the three regions the first terms of the expansion in power of the inverse of Zeldovich number,E/RT∞. In the expression that relates the vaporization rate and the Damköhler number, the flame temperature, θf, in first approximation, and the correctionH1f, due to the leakage of fuel by the flame appear. In the text we have mentioned the effect of the Lewis number, the physi-chemical parameters and the global reaction order on the process of ignition, extinction and combustion of monopropellent droplets. |
