Investigation of finite-volume methods to capture shocks and turbulence spectra in compressible flows 可压缩流动中捕捉激波和湍流谱的有限体积方法研究

Author(s): Motheau, E; Wakefield, J | Abstract: © Mathematical Sciences Publishers. The aim of the present paper is to provide a comparison between several finitevolume methods of different numerical accuracy: the second-order Godunov method with PPM interpolation and the high-order finite-volume WENO method. The results show that while on a smooth problem the high-order method performs better than the second-order one, when the solution contains a shock all the methods collapse to first-order accuracy. In the context of the decay of compressible homogeneous isotropic turbulence with shocklets, the actual overall order of accuracy of the methods reduces to second-order, despite the use of fifth-order reconstruction schemes at cell interfaces. Most important, results in terms of turbulent spectra are similar regardless of the numerical methods employed, except that the PPM method fails to provide an accurate representation in the high-frequency range of the spectra. It is found that this specific issue comes from the slope-limiting procedure and a novel hybrid PPM/WENO method is developed that has the ability to capture the turbulent spectra with the accuracy of a high-order method, but at the cost of the second-order Godunov method. Overall, it is shown that virtually the same physical solution can be obtained much faster by refining a simulation with the second-order method and carefully chosen numerical procedures, rather than running a coarse high-order simulation. Our results demonstrate the importance of evaluating the accuracy of a numerical method in terms of its actual spectral dissipation and dispersion properties on mixed smooth/shock cases, rather than by the theoretical formal order of convergence rate.
作者:Motheau, E;Wakefield, J |摘要:©Mathematical Sciences Publishers。本文的目的是提供几种不同数值精度的有限演化方法的比较:二阶Godunov方法与PPM插值和高阶有限体积WENO方法。结果表明,在光滑问题上,高阶方法优于二阶方法,但当解中含有激波时,所有方法均降至一阶精度。在具有激波的可压缩均匀各向同性湍流衰减的背景下,尽管在单元界面处使用了五阶重建方案,但方法的实际总体精度降至二阶。最重要的是,无论采用何种数值方法,湍流光谱的结果都是相似的,除了PPM方法无法在光谱的高频范围内提供准确的表示。本文提出了一种新的混合PPM/WENO方法,该方法能够以高阶方法的精度捕获湍流光谱,但以二阶Godunov方法为代价。总的来说,通过使用二阶方法和精心选择的数值过程来改进模拟,而不是运行粗糙的高阶模拟,可以更快地获得几乎相同的物理解。我们的结果表明,根据实际的谱耗散和色散特性来评估数值方法在混合光滑/激波情况下的准确性的重要性,而不是根据理论的收敛速率的形式顺序。

Author(s): Saye, RI | Abstract: © 2019 Mathematical Sciences Publishers. With an emphasis on achieving ideal multigrid solver performance, this paper explores the design of local discontinuous Galerkin schemes for multiphase elliptic interface problems. In particular, for cases exhibiting coefficient discontinuities several orders in magnitude, the role of viscosity-weighted numerical fluxes on interfacial mesh faces is examined: findings support a known strategy of harmonic weighting, but also show that further improvements can be made via a stronger kind of biasing, denoted herein as viscosity-upwinded weighting. Applying this strategy, multigrid performance is assessed for a variety of elliptic interface problems in 1D, 2D, and 3D, across 16 orders of viscosity ratio. These include constant-and variable-coefficient problems, multiphase checkerboard patterns, implicitly defined interfaces, and 3D problems with intricate geometry. With the exception of a challenging case involving a lattice of vanishingly small droplets, in all demonstrated examples the condition number of the multigrid V-cycle preconditioned system has unit order magnitude, independent of the mesh size h.

Computing the quasipotential for highlydissipative and chaotic SDEs an application to stochastic Lorenz’63 计算高耗散和混沌SDEs的准势及其在随机Lorenz ' 63中的应用

The study of noise-driven transitions occurring rarely on the time-scale of systems modeled by SDEs is of crucial importance for understanding such phenomena as genetic switches in living organisms and magnetization switches of the Earth. For a gradient SDE, the predictions for transition times and paths between its metastable states are done using the potential function. For a nongradient SDE, one needs to decompose its forcing into a gradient of the so-called quasipotential and a rotational component, which cannot be done analytically in general. We propose a methodology for computing the quasipotential for highly dissipative and chaotic systems built on the example of Lorenz'63 with an added stochastic term. It is based on the ordered line integral method, a Dijkstra-like quasipotential solver, and combines 3D computations in whole regions, a dimensional reduction technique, and 2D computations on radial meshes on manifolds or their unions. Our collection of source codes is available on M. Cameron's web page and on GitHub.
研究由SDEs模拟的系统在时间尺度上很少发生的噪声驱动转变,对于理解生物体内的遗传开关和地球的磁化开关等现象至关重要。对于梯度SDE,利用势函数预测其亚稳态之间的跃迁时间和路径。对于一个非梯度的SDE,我们需要把它的强迫分解成所谓的准势梯度和旋转分量,这在一般情况下是不能解析完成的。我们提出了一种计算高耗散和混沌系统的准势的方法,以Lorenz'63的例子为基础,增加了随机项。它基于有序线积分法、类dijkstra准势求解器,结合了全区域的三维计算、降维技术和流形或流形并集上径向网格的二维计算。我们收集的源代码可以在M. Cameron的网页和GitHub上找到。
