Figure extracted from Bobke et al., J. Fluid Mech. 820 (2017).

The database is described in:

A. Bobke, R. Vinuesa, R. Orlu and P. Schlatter. History effects and near equilibrium in adverse-pressure-gradient turbulent boundary layers. J. Fluid Mech., 820, 667-692 (2017).

The local edge velocity (Ue) and 99% boundary-layer thickness (delta99) were calculated using the method in:

R. Vinuesa, A. Bobke, R. Orlu and P. Schlatter. On determining characteristic length scales in pressure-gradient turbulent boundary layers. Phys. Fluids, 28, 055101 (2016).

The data is stored in .mat format

The two cases with constant beta are b1n and b2n.

The three cases with constant power-law exponent are m13n, m16n and m18n.

The data is organized into Matlab structures, where each entry is a streamwise position.

The database includes mean flow, Reynolds-stress tensor, integral quantities and turbulent kinetic energy budget terms.
