MEASUREMENT OF VELOCITY PROFILE AND DECAY OF VELOCITY FROM A RADIAL FLOW JET.
Abstract
The radial jet was developed by a flow of air exiting through a nozzle designed to turn the flow 90 degrees and establish a uniform profile. The flow field was measured with total pressure rakes. A hot-wire anemometer was used for certain profiles and center line decay. The center line was within 98% of the exit velocity until fully developed and then had a decay rate to the -1.2 power. The mixing region profile had a uniform section in the center and u/u sub-m = 1 - Tanh squared was a close approximation outside the center. The fully developed profile was between u/u sub-m = 1 - Tahn squared and u/u sub-m = 1 - 6y squared + 8y cubed - 3y to the 4th power. (Author)
