143 Swallowing flow simulation for the jelly bolus

Abstract

The swallowing flow was simulated to evaluate the safe care foods for the swallowing disorders. As the rheological model, a three-elements Maxwell model was applied to the jelly bolus, and the elastic model was applied to each part from mouth to esophagus. The friction between the bolus and the mucous surface was expressed using a static and a dynamic frictional coefficient. The simulated results approximately agreed with the results of the video fluolography.
