| 摘 要： | 为了分析复杂形式球型收敛调节片喷管(SCFN)三维内流场特性,对六角形和领结形的SCFN进行几何建模,并利用N-S方程和S-A模型,对两种喷管在不同落压比(NPR)下进行了内流场数值模拟.研究表明,计算结果与实验结果吻合较好;在此基础上,对两种喷管的流场特性及性能进行了比较分析.

| Abstract: | To analyze three-dimensional internal flow characteristic of spherical convergent flap nozzles with hexagonal and bowtie geometries,the geometric models were established and N-S equation and S-A model were employed in the numerical simulation.The simulation was developed at different NPR(nozzle pressure ratio).The calculated results are compared favorably well with experimental data.Furthermore,the internal flow characteristic and performance of two nozzles are compared and analyzed. |
