采用高阶守恒重映方法提高窗口嵌入技术中非点对点搭接网格界面的流场信息传递精度和分辨率,研究不同精度和模板选择方式下的重构对重映精度的影响.界面守恒变量的数据重构使用常数分布、线性分布和二次多项式分布.结果表明,基于WENO的线性重构在精度和计算量方面获得了较好的平衡.将改进的方法应用于机翼贴片修补问题的数值模拟,成功模拟出修补后翼面压力分布出现的明显跳跃.
The high-order conservation remapping method is used to improve the accuracy and resolution of flow field information in the non-point-to-point overlapping grid interface in the window embedding technique and the effect of reconstruction with different precision and template selection on the remapping accuracy is studied. The results show that the linear reconstruction based on WENO achieves a better balance between accuracy and computational complexity.The improved method is applied to the patch repair problem of wing The numerical simulations of the airfoils successfully simulate the apparent jump in the pressure distribution of the repaired airfoil.
