Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Diffusion limit of the compressible Euler-P1 approximation model arising from radiation hydrodynamics
辐射流体动力学 可压缩欧拉 近似模型 扩散极限
2023/5/8
We first show the nonequilibrium-diffusion limit of the compressible Euler-P1 approximation model arising in radiation hydrodynamics as the Mach number tends to zero when the initial data is well-prep...
The Second Conference of Global Chinese Scholars on Hydrodynamics (CCSH’2016)
chemical engineering energy exploration
2016/7/20
The Chinese Journal of Hydrodynamics (CJHD,《水动力学研究与进展》) (ISSN 1000-4874), formerly Journal of Hydrodynamics, Ser. A (in Chinese), started publication in 1986. An independent English periodical, the “J...
First-order moving least-squares are typically used in conjunction with smoothed particle hydrodynamics in the form of post-processing filters for density fields, to smooth out noise that develops in ...
Numerical Modelling of Contaminant Transport Hydrodynamics
runoff contamination environment numerical modelling real-time simulation forecasting hydrodynamic management
2015/8/14
Modelling of contaminant transport on watersheds is a problem of concern with regard to the protection of water ecosystems. This paper presents a numerical model, using the finite element method, to s...

The growth of central and satellite galaxies in cosmological smoothed particle hydrodynamics simulations
theory formation
2014/12/23
We examine the accretion and merger histories of central and satellite galaxies in a smoothed particle hydrodynamics (SPH) cosmological simulation that resolves galaxies down to 7 × 109 M⊙. Most frien...
Testing Subhalo Abundance Matching in Cosmological Smoothed Particle Hydrodynamics Simulations
