data for Targeted Mach Wave Elimination (TMWE)
This section presents selected data from the acoustic experiments on TMWE. The jet Mach number is 1.5 and its velocity is 700 m/s. The coflow is supplied at conditions simulating the unheated exhaust of fan at pressure ratio 1.9; its Mach number is 0.95 and velocity is 360 m/s. |
