moving boundary
3.Abstract: Three-dimensional,time-dependent,compressible fluid flow problems have been studied with the finite volume scheme based upon an arbitrary Lagrangian-Eulerian scheme.A general program for arbitrary mesh has been developed.This program can be used to the fluid flow with arbitrary shape boundary condition and moving boundary condition.As an example,the fluid flow in a simple tundish is calculated,and the time-dependent fluid flow distribution is given out.
4.When the conversations moves on to television, as it does regularly…(television and movies being the lingua franca of boys from six to that ever-moving outer boundary of adolescence)…, the boy is a dunce.
6.Also,a new contouring algorithm called moving-grid algorithm is described here which raises thespeed of contouring with high precision and is appliable for contouring in the region with compli-cate boundary.
7.This paper,with measuring stationary noise source and moving noise source for a premixed concrete plant,analyzed the major noise equipment and its influence on the noise environment of factory boundary,put forward the noise control method for the local sound insulation of main workshop and for the long acoustic insulation wall of ground moving noise source.
10.We shown that the Hamiltonian of the harmonic oscillator with time-dependent frequency and boundary conditions is related to the effective Harmiltonian of a particle in an infinite potential well with a moving wall by a time-dependent gauge transformation. Furthermore, we calculated the non-adiabatic Berry phase of wave function of the harmonic oscillator with time-dependent frequency and boundary conditions by using the geometric concepts such as the geometric distance and geometric length of the curve.
