Description	The article deals with the experimental research on a radial jet instability caused by the presence of an obstacle whose surface is parallel to the jet principal axis. The radial jet stability is crucial for the effective operation of an Aaberg exhaust hood; a special device of greater capture efficiency than that of traditional hoods. The radial jet constraints the flow, acting as a virtual flange, and entrains the surrounding fluid which results in a directional flow pattern in front of the hood. However, the jet stability depends on the presence of obstacles and is enhanced by the fact the hood removes air from the jet recirculation zone. By the jet instability, a such jet behaviour is called when the jet becomes attached to the obstacle surface thus departing from its original spreading direction. The reattachment might not be permanent giving rise to oscillatory flow (alternating attached and free jet states). The radial jet issued from a flange of 200 mm in diameter, its initial width being 4 mm The article deals with the experimental research on a radial jet instability caused by the presence of an obstacle whose surface is parallel to the jet principal axis.
