Study the air-flow structure, velocity field, temperature field, the degree of contamination and the law of heat exchange on the condition of convection. Then the results of numerical simulation are visualized, the law and character of airflow distribution and the application of displacement ventilation are discussed.
At the same time, the results of simulation proved that displacement ventilation is truly good designing project of airflow in conditioning room, can improve the quality of air in room, and can make personnel live in fresh air.

In this paper, the numerical approximation by Galerkin method for completely compressible miscible displacement with molecular diffusion and dispersion in porous media is considered.
In this paper, the problem of the antisymctrical small deflection of isotropic sandwich plates (in the theory of E. Reissner[1]) is reduced to the solution of two displacement-functions w and f, where to satisfies a differential equation of fourth order, and f satisfies a differential equation of second order. For a simply supported polygonal sandwich plates, it is proved that / vanishes identically, and the relation between w and the deflection w0 of a similar single-layered thin plates is establishe...
The purpose of this article is to clarify the various characteristic frequencies of a linear single degree of freedom mass spring system with viaoous damping. The frequencies are: undamped frequency ω0 ( resonant frequency, phase resonant frequency, velocity amplitude resonant frequency ) , natural frequency ωn, ( displacement ) amplitude resonant frequency Ωad and acceleration amplitude resonant frequency Ωaa.When the viscous damping is small, the differences among those frequencies are of no importa...
This paper deals with elastic contact problems, which belongs to category of. geometrical nonlinearity with small deformation. The nonlinearity of elastic contact problems is due to the contact conditions of the points contacted. The mixed approach suggested by this paper are suited for solving the local nonlinear problems. The general ideas of this mixed approach using F. F. M are as following: after the discretion of elastic bodies, according the displacement field assumed, we can get the stiffness ...
