The viscosity of liquid bolus is raised by thickener additives for patient with dysphagia. However the amount of the thickener additives has been decided by the experience. The appetite declines if the viscosity is raised too much. The method to decide the suitable viscosity is necessary. This study analyzed the swallowing flow using a finite element method. We produced the finite element model for the organs and conducted the coupled analysis between the organs and the liquid bolus. The relationship between the viscosity and the bolus velocity was discussed.
