| Abstract: | Objective To discuss the effect of different negative pressure to directional airflow in the main room of BSL-3 laboratory.Methods The author combined the experiment and numerical simulation in the study.Results Under the condition that the air supply volume in the main room of BSL-3 laboratory is ensured invariable,negative pressure is a critical factor to effect air distribution in the lab.Conclusion The simulation result shows that a good form of directional airflow under the condition of-50pa can come into being, which offers some reference to the engineering design. |
