| 摘 要： | 本文应用隐式有限差分理论对喷管内二维紊流流动进行了数值求解．采用了贴体曲线坐标系统，代数紊流方程模化紊流，整个流场用时间推进迭代方法获得．研究表明，控制方程右端粘性项矢是主变量欠的一个线性函数．文中所提供的计算方法与计算结果将为三维非定常计算打下基础．

| Abstract: | The two dimensional turbulent flow in a nozzle with curved boundaries is calculated in a body-fitted curvilinear coordinate by the approximate factorized finite difference scheme and algebraic turbulence model.The results show that the paper provides a solid base for further study on three dimensional problems. |
