【摘要】 网格插值方法是流固耦合领域的重点和热点。文中针对固液交界面上网格尺寸不一,网格节点不重合的情况,利用PCL和VC开发耦合边界的网格处理程序,通过适当的插值方法将流场计算结果插值到固体节点上,形成相应的边界条件。结合算例对比了流场计算结果与六面体Lagrange插值法、四面体体积插值法的计算结果,分析结果表明通过插值得到的结果云图与原始结果吻合,表明了本插值法的有效性及应用前景。更多还原

【Abstract】 Grid interpolation method is an important and complex issue in fluid-structure coupling field.Normally,grid sizes are different and the nodes are unmatched each other.In this paper,PCL and VC are used to develop a new grid interpolation program that can interpolate the results of fluid to structure nodes as loads,and complete the boundary conditions of structure model.Comparing fluid cloud diagram,hexahedron Lagrange interpolation cloud diagram and tetrahedron volume interpolation cloud diagram,the analysis shows its good consistency between original cloud diagram and interpolation cloud diagram.That means the method is valid and can be used in fluid-structure coupling analysis.更多还原
