【 摘 要 】

Natural ventilation is one of the main method of passive cooling for buildings, which is widely used in the Chinese colleges and universities classroom during the transitional seasons. To optimize the number of doors and windows in the classroom, the CFD (i.e. Computer Fluid Dynamics) method is used to study the wind speed effect on the flow distribution under the varying of windows and doors. The results show that with the number of people increasing, the indoor flow changes from constant to turbulent flow. This method and results can be used for the building design in the colleges and universities classroom.
