找了好久一直没有结果： A three dimensional computational fluid dynamics (3D-CFD) simulation of the 120mm gun bore evacuator flow cycle was performed using a finite element semi-discretization of the weak statement algorithm for mixed Euler/Navier-Stokes conservation laws. 几个有关的文章： 1.Combining Galerkin matrix perturbation with Taylor weak statement algorithms Subrata Roy Kettering University, Department of Mechanical Engineering, Flint, MI 48504-4898, USA Abstract For a large class of computational fluid dynamics (CFD) problems, the discrete approximate solution error is viewed as truncation of a Taylor series expansion. In this paper, a recently developed weak statement Galerkin Matrix Perturbation (GMP) method, is theoretically compared and combined with the well known Taylor Weak Statement (TWS) algorithm on a term by term basis yielding simple tridiagonal forms that reduce, or annihilate in special cases, the Taylor series truncation error. Verification hyperbolic solution is documented for a linear smooth and non-smooth incompressible wave cluster propagation using a combination algorithm of GMP and TWS. Keywords Taylor weak statement; Finite element; Static condensation; Matrix perturbation; High order accurate; Fully discrete 2.On convergence of Weak Thresholding Greedy Algorithm in L1(0,1) ☆ Smbat Gogyan Institute of Mathematics, Armenian Academy of Sciences, Marshal Bagramian street 24b, 375019 Yerevan, Armenia Abstract For any 0<t<1 we construct a Weak Thresholding Greedy Algorithm with weakness parameter t which converges in L1(0,1) with respect to the Haar system, i. e. the Haar system is a ‘good non quasi-greedy basis’. Keywords Haar system; Weak Thresholding Greedy Algorithm; Greedy Algorithm; Quasi-greedy basis; Convergence |
