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.
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.
