An analysis of discretizations of the Helmholtz equation in L 2 and in negative norms ( extended version )
نویسندگان
چکیده
For a model Helmholtz problem at high wavenumber we present a wavenumber-explicit error analysis in weak norms such as L, H. In 1D, we analyze the convergence behavior of the lowest order optimally blended spectral-finite element scheme of [Ainsworth & Wajid, SIAM J. Numer. Anal. (2010)].

متن کاملInvestigation of the efficiency of various reactive mufflers by noise reduction and transmission loss analyses
Transmission loss and noise reduction of reactive mufflers are determined by linear acoustic theory and unsteady flow field study, respectively. The effects of extending the inlet tube of the muffler, adding holes to the extension, and the number of holes on both transmission loss and noise reduction are investigated. In noise reduction analysis, the Navier-Stokes equations and k-ε model are us...

متن کاملAn efficient method for the numerical solution of Helmholtz type general two point boundary value problems in ODEs
In this article, we propose and analyze a computational method for numerical solution of general two point boundary value problems. Method is tested on problems to ensure the computational eciency. We have compared numerical results with results obtained by other method in literature. We conclude that propose method is computationally ecient and eective.
متن کاملApplication of Decoupled Scaled Boundary Finite Element Method to Solve Eigenvalue Helmholtz Problems (Research Note)
A novel element with arbitrary domain shape by using decoupled scaled boundary finite element (DSBFEM) is proposed for eigenvalue analysis of 2D vibrating rods with different boundary conditions. Within the proposed element scheme, the mode shapes of vibrating rods with variable boundary conditions are modelled and results are plotted. All possible conditions for the rods ends are incorporated ...
