Flutter prediction by an Euler method on non-moving Cartesian grids with gridless boundary conditions
收藏 引用
COMPUTERS & FLUIDS 2006年 第6期35卷 571-586页
作者: Kirshman, DJ Liu, F Univ Calif Irvine Dept Mech & Aerosp Engn Irvine CA 92697 USA
A method is presented for the prediction of transonic flutter by the Euler equations on a stationary Cartesian mesh. Local grid refinement is established through a series of embedded meshes, and a gridless method is i... 详细信息

BILINEARIZATION APPROACH FOR DIFFUSION problems INVOLVING THE CALCULATION OF DISSIPATIVE FIELDS
收藏 引用
numerical HEAT TRANSFER PART B-FUNDAMENTALS 2009年 第6期55卷 457-479页
作者: Mathieu-Potvin, Francois Gosselin, Louis Univ Laval Dept Genie Mecan Quebec City PQ GIV 0A6 Canada
A straightforward procedure is developed to determine dissipation fields (e. g., exergy destruction in conduction, pumping power, Joule heating) from the linear boundary conditions applied on their associated linear d... 详细信息

ASYMPTOTIC ANALYSIS 2005年 第4期43卷 287-322页
作者: Demengel, F Univ Cergy Pontoise F-95302 Cergy Pontoise France
In this paper we study necessary and sufficient conditions on f and the first eigenfunctions for the 1-Laplacian, for equations of the form [GRPHICS] when q =lambda(1), lambda(1) is the first eigenvalue for the 1-Lapl... 详细信息

On numerical solution of strongly anisotropic diffusion equation on misaligned grids
收藏 引用
numerical HEAT TRANSFER PART B-FUNDAMENTALS 2005年 第6期47卷 533-554页
作者: Umansky, MV Day, MS Rognlien, TD Lawrence Livermore Natl Lab Livermore CA 94550 USA
problems with extremely high-transport anisotropy often arise in strongly magnetized plasmas. The numerical solution of the highly anisotropic transport equations becomes quite difficult when the computational grid is... 详细信息

Axisymmetrical boundary-value problems of elasticity theory for finite-length cylinders and cones
收藏 引用
DOKLADY PHYSICS 2011年 第7期56卷 407-412页
作者: Popov, G. Ya. Mechnikov Natl Univ UA-65082 Odessa Ukraine
The article presents the solution for boundary-value problems of the elasticity theory of finite-length cylinders and cones to satisfy its axisymmetrical deformation. It says that the integral transform is applied to ... 详细信息

INTERNATIONAL JOURNAL OF QUANTUM CHEMISTRY 2004年 第3期100卷 245-253页
作者: Zhu, WM Trickey, SB Univ Florida Dept Phys Gainesville FL 32611 USA Univ Florida Dept Chem Quantum Theory Project Gainesville FL 32611 USA
We derive and test an approximate expression for the Kohn-Sham eigenfunctions and total energy associated with a given exchange-correlation functional. The expression is closely related to the approximation given by B... 详细信息
