本文通过建立数学模型,得到了侧上角送风-对侧下角回风洁净室在不同宽长比下的气流流型和速度场;进而分析了气流流型与房间尺寸之间的关系。本文还通过计算,给出了该洁净室所能达到的洁净度。
In this paper, by establishing a mathematical model, the airflow pattern and velocity field at the different width-length ratios of the air supply from the upper corner to the lower corner are obtained. Then the relationship between the airflow pattern and the room size is analyzed. This article also gives the cleanliness that the clean room can achieve through calculation.
