A low dissipation essentially non-oscillatory central scheme
نویسندگان
چکیده
Here we present a new, semidiscrete, central scheme for the numerical solution of one-dimensional systems of hyperbolic conservation laws. The method presented in this paper is an extension of the centrally weighted non-oscillatory schemes (Cweno) presented in [7], [5] and [6]. The method suggested in this manuscript is derived independently of the order of the scheme. The gain in this new method is a decreased dissipation especially for high Mach-number flows, which are frequently encountered, e. g., in astrophysical contexts or turbulent systems.

A low numerical dissipation patch-based adaptive mesh refinement method for large-eddy simulation of compressible flows
This paper presents a hybrid finite-difference/weighted essentially non-oscillatory (WENO) method for large-eddy simulation of compressible flows with low-numerical dissipation schemes and structured adaptive mesh refinement (SAMR). A conservative flux-based approach is described, encompassing the cases of scheme alternation and internal mesh interfaces resulting from SAMR. An explicit centered...
متن کاملThe comparison of two high-order semi-discrete central schemes for solving hyperbolic conservation laws
This work presents two high-order, semi-discrete, central-upwind schemes for computing approximate solutions of 1D systems of conservation laws. We propose a central weighted essentially non-oscillatory (CWENO) reconstruction, also we apply a fourth-order reconstruction proposed by Peer et al., and afterwards, we combine these reconstructions with a semi-discrete central-upwind numerical flux ...
متن کاملHigh-order Shock Capturing Schemes for Turbulence Calculations
The goal of this work is to investigate methods for simulating turbulent supersonic flows that include shock waves. Several different types of previously proposed characteristic filters, including total variation diminishing (TVD), monotone upstream-centered scheme for conservation laws (MUSCL), and weighted essentially non-oscillatory (WENO) filters, are investigated in this study. Similar to ...
متن کاملA new class of central compact schemes with spectral-like resolution II: Hybrid weighted nonlinear schemes
In this paper, we develop a class of nonlinear compact schemes based on our previous linear central compact schemes with spectral-like resolution [X. Liu, S. Zhang, H. Zhang and C-W. Shu, A new class of central compact schemes with spectral-like resolution I: Linear schemes, Journal of Computational Physics 248 (2013) 235-256]. In our approach, we compute the flux derivatives on the cell-nodes ...
متن کاملAn improved weighted essentially non-oscillatory scheme for hyperbolic conservation laws
We develop in this article an improved version of the fifth-order weighted essentially non-oscillatory (WENO) scheme. Through the novel use of higher order information already present in the framework of the classical scheme, new smoothness indicators are devised and we obtain a new WENO scheme with less dissipation than the classical WENO of Jiang and Shu [2], with the same computational cost,...
