This article introduced the using of computer simulation to analysis the design progress in 3 aspects: space efficiency, low running energy-consumption and innocuous design of the life-cycle of building; discussed the method of using appropriate low-cost technologies to save energy and make comfortable indoor environment of college sports buildings, and finally argued that using low-cost technologies is effective way to design a green college sports building.
In order to achieve the best energy-saving effect, the project took advantages of CFD simulation technology.

Thermal Flow Simulation The schematic drawing of vertical type twin-roll casting process is shown in Fig. 1.
Based on the assumptions steady-state simulations were performed.
The above simulation results show that the temperature distribution was non-uniform because of fixed dams and the different heat flux along roll width.
Experiments and simulation of thermal flow and solidification has verified the casting conditions and strip quality.

Based on computational fluid dynamics numerical simulation methods, this article studied the changes of resistance characteristics and tail pressure distribution on the 35° slant angle Ahmed model after installing the rear flaps.
Simulation Method As the automobile external flow is turbulent, RANS is used in research simulation.
Conclusions Different models were studied using numerical simulation methods to research the resistance characteristics and the change of static pressure distribution of the model with the tail installed clapboard, and to explain mechanism of drag reduction.
Simulation results show that only by designing the clapboard in accordance with parameter flow structure, that maximum drag reduction can be reached. 5.
