| A study was done to determine the converging distance of two axisymmetric turbulent jets and to compare the experimental results with the Reichardt hypothesis. This experiment consisted of measuring the velocity profiles of the two jets and manipulating the momentum ratio between the jets. Through testing, it was determined that the Reichardt hypothesis while efficient, over predicts the converging distance of the jets by up to 25% in some cases.;An Acoustic Doppler Velocimeter (ADV) was used to take measurements across the path of the jets and monitored the velocity and the turbulent kinetic energy. After observing the velocity profiles, I was able to distinguish a range at which the jets had converged.;Utilizing stepper motor technology, a total of 6064 data points were collected with each point requiring a two minute sampling time and one minute delay resulting in 303 hours of data collection. By using the stepper motors, the setup required 26 hours of time for setting the next stage of the experiment, approximately 8% of the total time requirement.;While errors did occur, as discussed in section 3.3, the setup is valuable in terms of the potential quality and amount of data that can be retrieved. Recommendations for future work are considered and listed based off of the experience of the researchers. |
