Abstract: The flow characteristics of an air jet exiting from a rectangular nozzle of aspect ratio 6.0 in a confined test rig with target were studied. A single hot wire was used to take measurements of the mean and root mean square (rms) velocities which correspond to inlet jet velocities of 10m/s and 20m/s. The results showed that the mean velocity profiles reach self preservation in the mixing layer at x/d=3 and x/d=4 for inlet jet velocity of 10m/s and 20m/s respectively. It was also observed that the decay rate and Reynolds number have a positive relationship. An increase in Reynolds number will lead to an increase in decay rate. In addition, the spreading rate of the confined jet had an inverse relationship with the Reynolds number; whereby an increase in Reynolds number will cause a decrease in spreading rate.
