摘要
对典型的地下室通风进行了数值模拟,模型采用紊流的k-ε双方程模型,得到在气流影响下有固定污染源的室内浓度分布,并分析比较了三种送排风方式下的通风效率,得出在送风量一定的方式下排污效率较高的通风方式,从而为通风优化设计提供了一定的参考。
A numerical analysis of the ventilation of typical underground - chamber has been made in this thesis. By adopting the k - ε two - equation turbulence model, the distributions of the contaminant concentration of the chamber with a stable fixed pollutant emission are calculated, and a better desired ventilation form is acquired by comparing the three Ventilation efficiency values of the different ventilation forms at the same of the air volume, which could provide some reference for the optimum ventilation design.
