This paper describes the project overview,the design of the cold source,air-conditioning,ventilation and smoke extraction system,as well as the design of air distribution simulation,sound attenuation and vibration isolation.

Microstructure simulation in welding lCrl8Ni9Ti steel;

The development condition of rolling theory is introduced with respect to mechanics analysis, microstructure simulation and system simulation.

Best fire monitor way under different air distribution in gymnasiums;

Study on CFD numerical simulation and air distribution of delaminated air-conditioning;

CFD simulation for the air distribution in a gymnasium;

Reasonable airflow organization is a mostly content in design of airflow in air-conditioned room, which not only effects design parameters of air-conditioned room, but also heavily effects reasonable operation of whole air-conditioned system.

Introduced the air condition design of Zhangjiagang broadcasd-TV building,and explained some special issues such as design parameter,airflow organization,noise control,which were different from common civic buildings.

The paper presents the methods which are used to simulate the airflow of turbulence in refurbishing materials supermarket,discusses the popular k ? ε model of high Reynold numberang the ways of numerical calculation,points out the troubles which are to solved during simulating the airflow organization.
