...Pramod B. Salunkhe; A. M. Pradeep The present paper describes the use of Morlet wavelet transform in understanding the stall inception mechanism in a single stage axial flow fan. Unsteady pressure data from wall mounted sensors were used in the wavelet transforms. This paper was carried out under...

... methods. Local time scales are defined as those of the most energetic fluctuations, and are calculated from wavelet transforms of the velocity signals. The dominant time scales are mapped as functions of the distance to the plate, the downstream location, and the phase relative to the wake-passing...

...Motoaki Kimura; Masahiro Takei; Chih-Ming Ho; Yoshifuru Saito; Kiyoshi Horii The two-dimensional low-speed structure of a turbulent boundary layer has been clearly visualized by a combination of a shear stress sensor using micro electro mechanical systems and the discrete wavelet transform...

...Heather L. McClusky; Mary V. Holloway; Donald E. Beasley, Fellow ASME; Jay M. Ochterbeck Continuous wavelet transforms are employed to determine the time-localized frequency content (scalogram) of instantaneous wall pressure signals in upward gas-liquid flow. The flow conditions correspond to well...
