The difference of the velocity boundary profile in curved TC flow as compared to plane Couette flow is more pronounced at small radius ratios. We propose to measure boundary layer properties in highly turbulent Taylor-Couette systems with small radius ratios using high-resolution particle image velocimetry. The idea is to study how the curvature affects the boundary layer profiles in strongly turbulent Taylor-Couette Flow. In the present work, we will mainly investigate the inner and outer boundary layer properties of Taylor-Couette flows in ultimate state.
