Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：A decoupled, linear, and unconditionally energy stable finite element method for a two-phase ferrohydrodynamics model
两相铁 流体动力学模型 无条件能量稳定 有限元方法
2023/4/28
In this talk, we present numerical approximations of a phase-field model for two-phase ferrofluids, which consists of the Navier-Stokes equations, the Cahn-Hilliard equation, the magnetostatic equatio...
Nonlinear Dynamics and Alternative Stable States in Shallow Coastal Systems
Shallow Coastal Systems Nonlinear Dynamics
2015/7/16
The dynamics of shallow-water coastal environments are controlled by external drivers—sea level rise, storms, and sediment and nutrient supplies—and by internal feedbacks. Interactions of biotic proce...
Energy Stable Flux Reconstruction Schemes for Advection–Diffusion Problems on Tetrahedra
High-order Unstructured Discontinuous Galerkin Spectral difference Flux reconstruction · Tetrahedra
2015/7/3
The flux reconstruction (FR) methodology provides a unifying description of many high-order schemes, including a particular discontinuous Galerkin (DG) scheme and several spectral difference (SD...

The authors recently identified an infinite range of high-order energy stable flux reconstruction (FR) schemes in 1D and on triangular elements in 2D. The new flux reconstructi...
Lévy stable distribution and [0,2] power law dependence of acoustic absorption on frequency in various lossy media
Lévy stable distribution [0,2] power law dependence acoustic absorption various lossy media
2010/10/22
Absorption of acoustic wave propagation in a large variety of lossy media is characterized by an empirical power law function of frequency, 0j!jy. It has long been noted that the exponent y ranges fr...
