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 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...
Dynamical energy analysis for built-up acoustic systems at high frequencies
Dynamical energy analysis built-up acoustic systems high frequencies
2010/12/16
Standard methods for describing the intensity distribution of mechanical and acoustic wave fields in the high frequency asymptotic limit are often based on flow transport equations.
Energy Spectrum of Quasi-Geostrophic Turbulence
Energy Spectrum Quasi-Geostrophic Turbulence
2014/4/4
We consider the energy spectrum of a quasi-geostrophic model of forced, rotating turbulent ow. We provide a rigorous a priori bound E(k) Ck2 valid for wave numbers that are smaller than a wave number...
