New dynamic digestion model reactor that mimics gastrointestinal function

A new dynamic model that mimics gastrointestinal function was designed. Elastic and contractile silica gel with gastrointestinal rugae and folds were used to simulate the stomach and large intestine, and silica gel with intestinal folds and villi was utilized to simulate small intestines. Mixing times for Newtonian fluids with Reynolds numbers of 10–5000 and for non-Newtonian fluids with Reynolds numbers of 1–100 were shortened in the new...
