Turbulence intensity profile in high Reynolds number pipe flow

Wada, Yuki ; Furuichi, Noriyuki*; Kusano, Eisuke*; Tsuji, Yoshiyuki*

This paper reports characteristics of turbulence intensity profile obtained in high Reynolds number actual flow facility in Japan. The experiments were performed in a pipe flow with water, and the friction Reynolds number was varied up to $Re_{tau}$ = 2.0 10 $^{4}$ . The streamwise velocity was measured by laser Doppler velocimetry (LDV). The new procedure to correct the measurement volume effect of LDV is suggested and we discuss turbulence intensity issues such as the inner peak Reynolds number dependence and the outer logarithmic behavior, it was found that these characteristic behaviors are consistent with previous turbulence studies.
