Abstract: Experimental investigation of the lateral jet interaction have beenperformed in supersonic flows to study the effects of jet pressures, angleof attacks, leeward side jet or windward side jet on the jet interactioncharacteristics. The results indicated that with increasing of jetpressures, the high pressure region before lateral jet extended forward, andthe wraparound effect strengthened. In the case of angle of attacks, thehigh pressure region before the leeward side jet enlarged, the region of jetwraparound effect moving forward, and the jet interaction control was moreeffective.
