针对燃烧室本身旋转和使用单组元液体推进刘的特点,对此两相湍流反应流在质量、动量和能量传输基础上,建立了旋转燃烧室中单组元液体推进剂雾化燃烧过程计算的模型和边界条件。模型计算采用SIMPLE算法和PSIC算法。计算结果提供了不同转速下的气相速度场和燃料浓度场。实验结果与计算结果一致。计算结果不仅反映了旋转对燃烧的明显影响,还说明本文的研究能用于预示和分析类似问题。
In view of the characteristics of the combustion chamber itself rotating and using a single component liquid to propel Liu, the two-phase turbulent flow was established on the basis of mass, momentum and energy transfer, and the calculation of the atomization combustion process of the single component liquid propellant in a rotating combustion chamber The model and boundary conditions. Model calculation using SIMPLE algorithm and PSIC algorithm. The calculated results provide the gas velocity field and the fuel concentration field at different speeds. The experimental results are consistent with the calculated results. The calculation results not only reflect the obvious influence of rotation on combustion, but also prove that the study in this paper can be used to predict and analyze similar problems.
