| dc.description.abstract | Normal and abnormal swallowing (dysphagia) processes in the pharynx were modeled using the computer-aided engineering software, FIDAP. In the normal case, boundary conditions for the epiglottis were established to prevent fluid flow into the larynx/trachea area. In the abnormal case, the boundary conditions for epiglottis were changed to allow some flow into the larynx/trachea. The program converged successfully when the mesh was simplified, and two distinct flow patterns were observed for both normal and abnormal cases. Sensitivity analysis of abnormal swallowing behavior showed that the flow present in the trachea was slower at higher viscosities. This suggests that the method of feeding dysphagia patients with thickened liquids is useful in preventing aspiration. | en_US |
