基于敏感性分析的DF化学动力学模型的简化
Simplification of a DF Chemical Laser Kinetic Model Based on the Sensitivity Analysis
摘要
Abstract
Based on die detailed DF chemical kinetic models of two different fuel systems, the relevant simplified chemical kinetic mechanisms were presented with the method of sensitivity analysis. It is found that considering the DF "cold reaction" pumping reactions, ignoring DF higher excited vibrationsl states and omitting me recombination-dissociation reactions have little effect on the total system. Hie energy transfer reactions in DF and DF deactivations by D, D2 and HF exhibits strong sensitivity to the chemical kinetics. Compared with the detailed mechanism, the simplified mechanism describes the general DF combustion process effectively, and at the same time reduces the species, element reactions and computational costs to a great extent. Therefore it fits more with coupling with three-dimensional flowfield numerical simulation code or software.关键词
