摘要
采用Jamson提出的有限体积法对 4种结构的轴对称推力矢量喷管的内流场进行了数值分析 ,预测了其内流场性能参数 ,计算结果与参考文献符合的很好 ,表明该方法对建立轴对称推力矢量喷管的数学模型具有很高的模拟精度和较快的收敛速度。
The finite volume method which is proposed by A. Jamson has been used to simulate numerically the interior flow-fields of four axisymmetric thrust-vectoring nozzles. The performance parameters of internal flow-fields have been predicted, and the results have showed satisfactoryagreement with the experimental results. The method is valid for the establishment of mathematics models of axisymmetric thrust-vectoring nozzles with favorable simulated accuracyand convergence rate.
