    Abstract
  • In order to investigate the influence of self-coupling jet on the vectoring of the primary jet,parallel jets arrangement were adopted.The self-coupling jet exciter is parallel to the primary jet and the formation of a low-pressure region between the jets results in a deflection of the primary jet towards the exciting jet.The PIV experimental study shows that for f=400 Hz,the momentum flux of the self-coupling jet achieves its maximum value,while the boundary of the primary jet reaches its maximum width due to the strongest suction ability to the environmental gas.However,the experiment indicates that for f=500 Hz,due to the self-coupling jet exciting,the maximum 48° vectoring of the primary jet with a flow speed of 2.6 m/s achieves.
