A theoretical and experimental study of the impingement of two subsonic jets
A theoretical and experimental investigation has been performed on the determination of the characteristics of two impinging plane turbulent jets for the purpose of under1tanding the performance of proportional fluid amplifiers and momentum-exchange devices . The jet deflection angle was determined through the application of the free-streamline theory for two normally impinging jets with arbitrary throat widths and wall set-backs . The deflection angle and the velocity and turbulence distributions acro1s and at various distances along the jet were determined through the use of a hot-wire anemometer system. The results are presented in terms of normalized parameters suitable for comparison with the theoretical predictions. The deflection angles predicted theoretically were found to be in good agreement with those obtained experimentally.
