Fig. 2From: Contributions of the microbiome to intestinal inflammation in a gut-on-a-chipSimulation of a gut-on-a-chip under various fluidic flows and geometric conditions. A Wall shear stress is calculated with respect to the height of the microchannel. B Wall shear stress is calculated with respect to the width of the microchannel. C Wall shear stress is calculated with respect to the distance between the micropillars. D Flow speed distribution in the cell culture microchannel. CFD simulations were performed to analyze the velocity at various concentrations of 0.18 M, 0.36 M, 0.72 M PEG solutions. E Velocity distribution inside the microchannel is calculated in a section of A–DBack to article page
