中文摘要:
      基于动气动弹性仿真中二维动网格方法的研究,提出了一种三维动网格生成技术,该方法的主要特点是在计算域内利用原有的初始网格进行插值计算来构造新网格。对于流体-结构耦合中每时间步长计算的动网格算法主要考虑网格的稳定性和计算效率。最后,选取了二维、三维中一些有代表性的实例进行了演示,结果表明对于变形量不是很大的情形是令人满意的。
英文摘要:
      Based on the study of the two-dimensional moving meshes in dynamic aeroelastic interaction simulation, a three-dimensional moving grid enrichment approach is developed and illustrated in this paper .The key advantage of this approach is that the meshes interpolated in the computational domain is utilized to remap the flow variables from the old mesh to the new. The robustness and efficiency for coupled structure-fluid time marching computations have been emphasized in mesh deformation algorithm. Examples representating 2D and 3D flow problems are demonstrated,which shows the effictiueness of the approach.The results are satisfactory in the case of small amplitude displacement.
