| 中文摘要: |
| 给出了带襟翼偏转的三维机翼绕流的一种求解Ｎ－Ｓ方程的计算方法，采用区域求解算法和对接分区网络技术相结合的方法，有效地求解了绕此外形的复杂流动，区域求解算法中提出了一种满足通量守恒的内边界耦合条件，流场求解时采用中心差分的限体积方法对空间通量顶进行离散，采用显式推进方法进行时间方向的积分，数值算例表明本方法是求解带襟翼偏转的机翼绕流的有效方法。 |
| 英文摘要: |
| A N\|S method for solving the flow around a wing with deflection of flap is presented. Using the combination of patched grid and domain decomposition techniques, the complex flow around this kind of configuration is effectively solved. An internal coupling condition satisfied the conservation of flux is used in the domain decomposition method. The spatial flux terms are discretized by using central difference scheme and the time integration is performed by using explicit scheme in the flow solver. Numerical results show that the present method is effective one for solving the flow around wing with flap deflection. |
