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.   An immersed boundary method based on discrete stream function formulation for two- and three-dimensional incompressible flows 期刊论文  OAI收割 Journal of Computational Physics, 2011, 卷号: 230, 期号: 9, 页码: 3479-3499 作者:  Wang SZ(王士召);  Zhang X(张星) 收藏  |  浏览/下载：24/0  |  提交时间：2012/04/01 Immersed Boundary Method  Discrete Stream Function Formulation  Incompressible Flow  Navier-Stokes Equations  Parallel Computing  Large-Eddy Simulation  Cartesian Grid Method  External Force-Field  Low-Reynolds-Number  Circular-Cylinder  Interface Method  Conservation Properties  Numerical-Solutions  Moving Boundary  Viscous-Flow   THE APPLICATION OF THE NEARLY OPTIMAL SPONGE BOUNDARY CONDITIONS FOR SEISMIC WAVE PROPAGATION IN POROELASTIC MEDIA 期刊论文  OAI收割 JOURNAL OF SEISMIC EXPLORATION, 2010, 卷号: 19, 期号: 1, 页码: 1-19 作者:  Chen, Jingyi;  Bording, Ralph Phillip;  Liu, Enru;  Zhang, Zhongjie;  Badal, Jose   |  收藏  |  浏览/下载：15/0  |  提交时间：2018/09/26 Boundary Conditions  Numerical Modeling  Poroelastic Media  Biot/squirt Mechanism  Staggered-grid Finite-difference   THE APPLICATION OF THE NEARLY OPTIMAL SPONGE BOUNDARY CONDITIONS FOR SEISMIC WAVE PROPAGATION IN POROELASTIC MEDIA 期刊论文  OAI收割 JOURNAL OF SEISMIC EXPLORATION, 2010, 卷号: 19, 期号: 1, 页码: 1-19 作者:  Chen, Jingyi;  Bording, Ralph Phillip;  Liu, Enru;  Zhang, Zhongjie;  Badal, Jose   |  收藏  |  浏览/下载：22/0  |  提交时间：2018/09/26 Boundary Conditions  Numerical Modeling  Poroelastic Media  Biot/squirt Mechanism  Staggered-grid Finite-difference
