Abstract

This paper presents the velocity measurements of an unheated jet issuing from a square nozzle into stagnant ambient air. Measurements were accomplished by means of hot-wire anemometer. Experimental results concluded that the jet initial boundary layer was laminar. Based on the local maximum velocity and half-width, the interaction region was determined to be 8De. Decay and spreading rates of the jet were also studied and compared with those of other researchers. Lastly, plots of velocity half-width profiles predicted that there may be no axis-switching in the present square jet although more measurement evidence is required.
