Dataset supporting the publication "Mean flow of turbulent boundary layers over porous substrates"

Abstract

This dataset supports the following publication: L. B. Esteban, E. Rodriguez-Lopez, M. A. Ferreira and B. Ganapathisubramani, "Mean flow of turbulent boundary layers over porous substrates", Phys. Rev. Fluids, 2022 DOI: 10.1103/PhysRevFluids.00.004600 This dataset contains .mat files which has all the mean velocity profiles as well as the information on other scaling quantities such as skin-friction velocity, boundary layer thickness, kinematic viscosity and free stream velocity to obtain the different plots presented in the paper. The data is presented in three different .mat files, one for each of the three different porous/permeable substrates examined in the study. Measurements of turbulent boundary layer flow over all three porous substrates (10PPI, 45PPI and 90PPI) with two different thicknesses (3mm and 15 mm) have been performed using hot-wire anemometry and skin-friction drag-balance. The data presented provides profiles of mean velocity obtained using hot-wire measurements for the three cases at three different freestream velocities (10 m/s, 18 m/s and 26 m/s). The specifics of the data is self-evident upon using the data from the three different mat files.
