A turbulence generator was embedded in a nozzle which was designed for an experimental study on the effects of gas turbulence on liquid breakup and atomization. Using this experimental nozzle, it was possible to change the turbulence intensity at the nozzle exit without changing the mean velocity or the Reynolds number. It was also possible to vary the mean exit velocity while maintaining either the rms velocity or the turbulence intensity unchanged. The operation of the turbulence generator is controlled by several upstream pressure regulators which affect the internal flow pattern and determine the flow conditions at the nozzle exit. The free jet which was generated by the nozzle was studied in detail and measurements of mean and rms velocities, turbulence kinetic energy, Reynolds stresses, and turbulence production are presented. It was concluded that the new turbulence generator can be used effectively for both research and industrial applications.
