Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Geometric regularity criteria and inviscid limit of incompressible Navier--Stokes Equations under Navier boundary condition
Navier边界条件 不可压缩 Navier-Stokes方程 几何正则性准则 无粘极限
2023/11/29
We report our recent works on the analysis of 3D incompressible Navier--Stokes Equations subject to the Navier slip boundary condition, i.e., tangential components of the stress exerted by the normal ...
Choice of the perfectly matched layer boundary condition for frequency-domain Maxwell’s equations solvers
Maxwell’s equations Perfectly matched layer Finite-difference frequency-domain method
2015/8/7
We show that the performance of frequency-domain solvers of Maxwell’s equations is greatly affected by the kind of the perfectly matched layer (PML) used. In particular, we demonstrate that using the ...
Identification of boundary condition on the contact surface of continuous casting mould
Application of information technology to the foundry industry Solidification process
2011/3/11
In the paper the methods of inverse problems solution are applied for the identification of substitute heat transfer coefficient in the primary cooling zone of continuous casting plant.
Ultrasonic beam steering using Neumann boundary condition in multiplysics
Ultrasonic beam steering Desired angle Line element time-delay
2012/2/24
The traditional one-dimensional ultrasonic beam steering has time delay and is thus a complicated problem. A numerical model of ultrasonic beam steering using Neumann boundary condition in multiplysic...
Influence of thermal boundary condition on casting process of metal matrix composite
Casting Solidification Metal matrix composite Contact resistance CFD simulations
2010/8/17
The specific properties of metal matrix composites largely depend on the applied type of material, of which the matrix and reinforcement are made. Recently, a great interest is observed in the composi...
Application of a perfectly matched layer boundary condition to finite element modeling of elastic wave scattering in cracked plates
perfectly matched layer finite element modeling elastic waves plates
2010/9/27
This paper investigates the applicability of a displacement-based, Finite Element (FE) implementation of a time-domain, split-field Perfectly Matched Layer (PML) formulation to numerical modeling of e...
MELTING AND FREEZING IN A FINITE SLAB DUE TO A LINEARLY DECREASING FREE-STREAM TEMPERATURE OF A CONVECTIVE BOUNDARY CONDITION
finite slab freezing heat balance integral
2009/10/14
One-dimensional melting and freezing problem in a finite slab with time-dependent convective boundary condition is solved using the heat-balance integral method. The temperature, Tinf 1(t), is applied...
