Paper No: FEDSM2002-31121
... to investigate the principal motion of the velocity field, phase averaging was conducted to the velocity signals obtained by single hot-wire measurement. In phase averaging, wavelet analysis was applied to obtain the dominant frequency and the characteristic phase in the fluctuation. The profiles...

Proc. ASME. FEDSM2003, Volume 2: Symposia, Parts A, B, and C, 261-266, July 6–10, 2003
Paper No: FEDSM2003-45032
... By using phase averaging technique, turbulent structure in a flow was studied. For the phase angle of the time dependent signal modulated in frequency, data acquisition is difficult. This study proposed a new method of phase averaging by wavelet transformation. The purpose of the present study...
