A numerical dataset for low Reynolds number unidirectional oscillating flow through a porous material

High-fidelity simulation data of a unidirectional oscillating flow through a porous material sample for several oscillation frequencies of a weakly aerodynamic amplitude. The porous material sample is an alternate diamond of the triply periodic minimal surface family with a unit cell size of 2 mm tiled into a porous material sample of 20 mm x 8 mm x 8 mm. The simulation domain is periodic in the cross-flow axes, resulting in planar oscillatory waves.
