摘要: We present an experimental investigation and data analysis of a turbulent boundary layer flow at significant adverse pressure gradient for two Reynolds numbers \(Re_\theta =6200\) =8000\). perform detailed multi-resolution measurements by combining large-scale long-range microscopic particle imaging. investigate scaling laws the mean velocity total shear stress in inner layer. In part can be fitted log-law. outer modified log-law provides good fit, which depends on parameter inertial effects. Emphasis is number effects stress.
