Rms velocity fluctuation
WebFluctuations of equivalent NCO frequency (velocity) was studied in statics for the same combinations as 22 0.17 0.25 loss 2 2 18 0.26 0.33 in experiment 1. Some information on RMS = EV + STD (wherein EV is expected value, STD is standard deviation, RMS 14 loss loss is root mean square) of fluctuations of equivalent NCO frequency is given in Table VIII. WebSince there was a lack of high-frequency inflow velocity fluctuation measurements in the field experiments, pressure fluctuations from the surface microphones in the laminar boundary layer close to the leading edge are used to analyze the inflow turbulence characteristics in detail (Madsen et al., 2024).
