Conjugate lter approach for shock capturing †
نویسندگان
چکیده
This paper introduces a new scheme for the numerical computation involving shock waves. The essence of the scheme is to adaptively implement a conjugate low-pass lter to e ectively remove the accumulated numerical errors produced by a set of high-pass lters. The advantages of using such an adaptive algorithm are its controllable accuracy, relatively low cost and easy implementation. Numerical examples in one and two space dimensions are presented to illustrate the proposed scheme. Copyright ? 2003 John Wiley & Sons, Ltd.

Shock-capturing with natural high-frequency oscillations
This paper explores the potential of a newly developed conjugate lter oscillation reduction (CFOR) scheme for shock-capturing under the in uence of natural high-frequency oscillations. The conjugate lowand high-pass lters are constructed based on the principle of the discrete singular convolution (DSC), a local spectral method. The accuracy and resolution of the DSC basic algorithm are accessed...
متن کاملDeveloping a Shock-Capturing Formulation with Higher Performance to Capture Normal Standing Shock in All-Speed Regime
The main objective of the present study is to utilize a novel linearization strategy to linearize the convection terms of the quasi-one-dimensional Euler governing equations on collocated grids and to examine its shock-capturing capabilities. To avoid a pressure checkerboard problem on the collocated grids, it is necessary to utilize two velocity definitions at each cell face. Similarly, we def...

متن کاملConstraint in Shock - Capturing Magnetohydrodynamics Codes
Submitted to the Journal of Computational Physics Seven schemes to maintain the r B = 0 constraint numerically are compared. All these algorithms can be combined with shock-capturing Godunov type base schemes. They fall into three categories: the eight-wave formulation maintains the constraint to truncation error, the projection scheme enforces the constraint in some discretization by projectin...
متن کاملA MODIFIED COMPRESSIBLE SMOOTHED PARTICLE HYDRODYNAMICS (MCSPH) METHOD AND ITS APPLICATION ON THE NUMERICAL SIMULATION OF LOW AND HIGH VELOCITY IMPACTS
In this study a Modified Compressible Smoothed Particle Hydrodynamics (MCSPH) method is introduced which is applicable in problems involve shock wave structures and elastic-plastic deformations of solids. As a matter of fact, algorithm of the method is based on an approach which descritizes the momentum equation into three parts and solves each part separately and calculates their effects on th...
