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°.
随着两射流轴心间距增加,双风幕效果迅速提高;当轴心间距增大到某一值之后,双风幕效果缓慢下降;双风幕的动力性能与射流喷射角有关,喷射角应在15°～22°之间。
