Experimental investigation of primary flow vectoring using parallel self-coupling jets
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.
