This paper presents the velocity and temperature measurements of a heated jet issuing from a square nozzle into stagnant ambient air. Measurements were accomplished by means of hot-wire and cold-wire anemometers. Experimental results showed that the jet initial boundary layer was laminar. Based on the local maximum velocity and half-width, the interaction region was determined from 5De to 8De. It is found that the temperature has higher spreading rate and root mean square values than those of the velocity. It is thus suggested that the heated jet could enhance the mixing better.
