摘要
提出了一种用边界层理论对轴对称弯曲流道内部流动进行分析的方法,即主流区用流线曲率法计算,边界层利用Partanker-Spolding方法,并采用了k-ε,紊流模式。在边界层方程组及k-ε方程中均考虑了轴对称情形下曲率的影响,并在紊流模式中考虑了曲壁对紊流结构的影响。此外还以“分离点的奇异性”预测了边界层的分离,给出了轴对称曲壁发生分离时型参数的大小。经实验与计算比较,结果令人满意。
This paper presents a method for the numerical analyse of viscous in compressible fluid flow in axisymmetric curvature passage. For main flow field computation, the stream line curvature method is used. Partankerspolding method and k-ε turbulent model are used for boundary layer. Under the axisymmetric situation, the effect of wall curvature has been considered in the set of boundary layer equations and k-ε equation. In turbulent modle the effect of curvature wall on the turbulence construction has also been considered.
