摘要
采用耦合显式格式的 Mac Cormack的时间推进预测 -校正两步有限差分格式求解 Navier- Stokes方程 ,化学反应采用 17种组分、12个反应的有限速率的化学反应模型。得到了流场参数在燃烧室中的分布情况。其结果同理论分析相一致 ,最后用实验验证了利用数值模拟方法的可行性及可信性。研究结果对火箭发动机的设计、性能预测。
This paper solves N-S equation by employing the MacCormak two step difference of the implicit coupled point. The combustion process is modeled by 17 specice, 12 step finite rate chemical model. The distribution of flow parameters is presented in combustion chamber. The results agree with the theoretical analysis . Finally the method of numerical simulation is validated by the experiment. The conclusions are of practical meaning and important reference to the design, improvement of performance and exploration of the rock motor.
