Pictures of the gut-on-a-chip prototype and illustrations of the computational domains. (a) The gut-on-a-chip prototype. (b) The electro microscopic image of the porous membrane in the gut-on-a-chip prototype. (c) The main microchannels in the gut-on-a-chip prototype with the block of computational domain shown in red. (d) The computational domain with the staggered porous membrane pattern. (e) The computational domain with the in-line porous membrane pattern. The black arrows indicate the direction of the main flow and the green arrows indicate the direction of peristalsis motion.
