Assessing inner boundary conditions for global coronal modeling of solar maxima
Michaela Brchnelova, Błażej Kuźma, Fan Zhang +3
Computational Fluid Dynamics (CFD)-based global solar coronal simulations are slowly making their way into the space weather modeling toolchains to replace the semi-empirical metho…
Improving the quantification of overshooting shock-capturing oscillations
Fan Zhang
An approach for quantitatively evaluating overshooting oscillations is designed to characterize the performance of shock-capturing schemes. Specifically, following our previous wor…
COCONUT, a novel fast-converging MHD model for solar corona simulations: I. Benchmarking and optimization of polytropic solutions
Barbara Perri, Peter Leitner, Michaela Brchnelova +5
We present a novel global 3-D coronal MHD model called COCONUT, polytropic in its first stage and based on a time-implicit backward Euler scheme. Our model boosts run-time performa…
On the numerical overshoots of shock-capturing schemes
Huaibao Zhang, Fan Zhang
This note introduces a simple metric for benchmarking shock-capturing schemes. This metric is especially focused on the shock-capturing overshoots, which may undermine the robustne…
Towards optimal high-order compact schemes for simulating compressible flows
Huaibao Zhang, Fan Zhang, Chunguang Xu
Weighted compact nonlinear schemes (WCNS) [Deng and Zhang, JCP 165(2000): 22-44] were developed to improve the performance of the compact high-order nonlinear schemes (CNS) by util…
An extending strategy based on TENO framework for hyperbolic conservation laws
Fan Zhang, Jun Liu, Huaibao Zhang +1
Recently, the targeted ENO (TENO) schemes give a novel framework to keep optimal high-order spatial reconstruction wherever discontinuity is deemed to be vanished, including at smo…
Modified multi-dimensional limiting process with enhanced shock stability on unstructured grids
Fan Zhang, Jun Liu, Biaosong Chen
The basic concept of multi-dimensional limiting process (MLP) on unstructured grids is inherited and modified for improving shock stabilities and reducing numerical dissipation on…
A vertex-weighted-Least-Squares gradient reconstruction
Fan Zhang
Gradient reconstruction is a key process for the spatial accuracy and robustness of finite volume method, especially in industrial aerodynamic applications in which grid quality af…
A simple field function for solving complex and dynamic fluid-solid system on Cartesian grid
Huangrui Mo, Fue-Sang Lien, Fan Zhang +1
In this paper, a simple field function is presented for facilitating the solution of complex and dynamic fluid-solid systems on Cartesian grids with interface-resolved fluid-fluid,…
An immersed boundary method for solving compressible flow with arbitrarily irregular and moving geometry
Huangrui Mo, Fue-Sang Lien, Fan Zhang +1
In this paper, a novel immersed boundary method is developed, validated, and applied. Through devising a second-order three-step flow reconstruction scheme, the proposed method is…
