Data underlying the publication: Wall shear stress measurement using a zero-displacement floating-element balance

The dataset includes direct measurements of the skin friction coefficient of the smooth-wall boundary layer using a zero-displacement floating element (FE) balance and oil film interferometry (OFI). The corresponding mean velocity profiles from hot-wire anemometry are also provided. The measurements cover a wide range of momentum thickness Reynolds numbers from 8800 to 35300. The experiment was designed to assess the performance of the newly developed FE balance, with OFI serving as the benchmark.
