屏蔽室通风仿真设计研究

Simulation Design Study of Shielded Room Ventilation

针对以往屏蔽室通风是根据经验布置,造成通风量不足或过设计等问题,以某项目屏蔽室为研究对象,利用CFD仿真技术,研究进出风口五种布置方式下屏蔽室通风量的大小。结果表明,方案一、方案二、方案三风阻最小,方案五次之,方案四风阻最大;进出风口按照方案一、方案二、方案三布置时,随着通风波导窗之间距离的增大风量减少;进出风口按照方案四布置时,随着通风波导窗之间的距离增大风量增加;进出风口按照方案五布置时,通风波导窗距离和通风量的关系不明显。该仿真试验研究可为屏蔽室通风进出风口设计提供仿真设计依据。

In response to the previous shield room ventilation is based on empirical arrangement,which can cause problems such as insufficient ventilation or over-design,the size of shield room ventilation under five arrangements of air inlet and outlet is studied by using CFD simulation technology with a project shield room as the research object.The results show that the wind resistance is the smallest in Scheme 1,Scheme 2 and Scheme 3,followed by Scheme 5,and the largest in Scheme 4;when the air inlet and outlet are arranged according to Scheme 1,Scheme 2 and Scheme 3,the air volume decreases as the distance between the ventilation waveguide windows increases;when the air inlet and outlet are arranged according to Scheme 4,the air volume increases as the distance between the ventilation waveguide windows increases;when the air inlet and outlet are arranged according to Scheme 5,the relationship between the distance between the ventilation waveguide windows and the ventilation volume is not obvious.The relationship between the distance between the ventilation waveguide windows and the ventilation volume is not obvious.The relationship between the distance‘between the ventilation waveguide windows and the ventilation-volume is not obvious when the air inlet and outlet are arranged according to Option 5.
