AbstractThis Excel sheet contains all raw data from which plots and calculations in the referenced publication have been generated. The scope of the paper is to investigate the influence of constrictivity (a measure for bottleneck effects in microstructures) on permeability. Using a stochastic 3D microstructure model, virtual microstructures with different values of constrictivity were generated. The parameter used for controlling constrictivity is the so-called core-shell ratio. For each of the five different core-shell ratios, 10 realizations of the model were drawn for which porosity and constrictivity were computed. Subsequently, permeability was determined using the finite volume method. For three chosen structures, experimental values of permeability were gained for validation purposes. This was done by 3D printing of the structures using selective laser melting, and subsequent experimental measurement of pressure drop. Moreover, the same three structures were transformed using a more complex strut model, and permeability was compared to the values for the structures with simple strut model. The results were used to empirically derive a relationship between constrictivity and permeability.dc.description.abstract
