PIV database of solid and porous airfoils in the wake of an upstream circular rod

This database includes the flow-velocity data presented in the companion paper "Experimental investigation of turbulent coherent structures interacting with a porous airfoil", which has been published in the journal "Experiments in Fluids". The measurements refer to three free-stream velocities, namely 20 m/s, 30 m/s, and 40 m/s, and to three different wing-profile configurations, namely a "solid", "porous", and "melamine" airfoil (as described in the paper). The data include 2D flow-velocity maps (expressed in m/s) for the streamwise and upwash velocity component (considering the reference system described in the paper) and two arrays of x- and y-coordinates for the definition of the spatial locations of the measurement points. Each velocity map refers to a different time step, for a total of 8000 time steps (1 s of acquisition with a sampling rate of 8 kHz). The present database is suitable for the application of the Proper Orthogonal Decomposition (POD) technique, as shown in the paper.
