【 摘 要 】

In experiment influence of the acoustic impact on streams reacting and nonreacting gases is investigated. Visualization of streams was carried out by a shadow method on the basis of the shadow IAB-451 device. It is revealed that in some cases at acoustic impact on a gas stream bifurcation of a stream is observed. Dependences of a corner of disclosure of a stream and distance are received from the open end of a tube to a place of division of a stream from the frequency of acoustic influence and level of sound pressure.
