The CFD solver is based on the finite-volume algorithm for the Navier-Stokes equations on unstructured grid. The CSD solver solves the aeroelastic governing equations in the modal space. Their coupling is realized by a dual-time method. The spring-based smoothing method is adopted to deform and regenerate the aerodynamic grid. Two test cases are selected to validate the authors' method for static and dynamic aeroelastity .The results of the simulation for the static aeroelastic problems of a missile wing show that the Lift Coefficient and Drag Coefficient are severally 7% and 5% lower than those don't consider the elasticity of the wing. The results for the flutter boundary prediction of the AGARD 445.6 wing have been proved much closer to the experiment than using the DLM. This method can describe the effects of fluid viscosity more exactly for highly nonlinear transonic flight conditions. The calculation has proved reliable in the subsonic regime  but not accurate enough in the supersonic regime. 2011 IEEE.   A defect correction scheme for finite element eigenvalues with applications to quantum chemistry 期刊论文 SIAM JOURNAL ON SCIENTIFIC COMPUTING, 2006, 卷号: 28, 期号: 1, 页码: 321-338 作者:  Shen, LH;  Zhou, AH 收藏  |  浏览/下载：16/0  |  提交时间：2018/07/30 defect correction  eigenvalue  finite element  Hartree-Fock equation  highly accurate  quantum chemistry   高精度散射光度滴定法在苯妥英钠含量测定中的应用 期刊论文 药学学报, 2006, 卷号: 第41卷, 页码: P370-375 作者:  YI Tao;  ZHAN Xiancheng;  LI Chengrong;  HE Ning 收藏  |  浏览/下载：1/0  |  提交时间：2019/02/28 highly accurate nephelometric titration　　phenytoin sodium　　solubility product constant　　colloid
