Abstract
Pressure fluctuations are measured in zero-pressuregradient boundary layers. Following the previous studies, we developed the small pressure probe and measure both the static pressure inside boundary layer and wall pressure simultaneously in turbulent boundary layers up to Reynolds numbers based on the momentum thickness Rθ ≈ 20000. Discussions are made on the background pressure in the free stream region. It contaminates the physical pressure in the boundary layer. We report on the pressure intensity profile normalized by outer and inner variables. Once the background pressure is subtracted, they are compared with the results of direct numerical simulations.
