采用态-态模型的热化学非平衡喷管流数值研究
|
摘要
数值求解耦合态-态模型的N2/N准一维喷管非平衡流方程,获得驻室温度3 000 K~10 000 K,压力1 atm~10 atm条件下的流场参数分布和详细的振动能级分布,分析喷管流动中的宏观和微观特性,并对这类复合占优的流动考察双温度模型中假设的合理性.
A state-to-state model is used to simulate thermochemical nonequilibrium nozzle flow of N2/N mixture. Quasi-onedimensional nozzle flow at reservoir temperature from 3 000 K to 8 000 K and pressure from 1 atm to 10 atm is simulated numerically to obtain flow properties,especially detail vibrational population distribution. Evolution of macro- and micro-properties of nonequilbrium flow during expanding is analyzed. Rationality of two-temperature or multi-temperature approach is investigated for recombination dominating flows.
