Rheological Characterization of Shear Thickening Fluids
On average, ten million Americans are evaluated every year for swallowing difficulties. Dysphagia is the medical term for difficulty in swallowing. Untreated dysphagia can lead to pulmonary aspiration and ultimately aspiration pneumonia due to presence of foreign material in the lungs. Thickened fluids are used to manage dysphagia. These thickening agents increase the stability of suspensions and create a weak gel structure. In this study, a series of thickening agents in varying concentrations were measured with a rotational rheometer. An array of rheological techniques, including LAOS, was utilized to probe the visco-elastic response of these materials at various temperatures in the life cycle of the product.
