Summary

This paper analyses the dynamic characteristics of dual-jet air curtains to defend against or reduce the transverse airflow, and compares with those of the single-jet air curtains. The result shows that, with the same jet conditions, the ability of slot dual-jet air curtains to resist the lateral pressure difference is stronger. The effect improves quickly before the spacing of jets increasing to a certain point and gradually declines. And the dynamic characteristic is related to the jet angle which is preferable to be in the range of 15 to 22°.
