143 ゼリー状食塊の嚥下流動シミュレーション(S34-4 複雑流体の流れとその応用(4),S34 複雑流体の流れとその応用)  [in Japanese] 143 Swallowing flow simulation for the jelly bolus  [in Japanese]

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.
