This work was aimed to study numerically the food bolus flow through the pharynx. Using a 2D geometry obtained elsewhere, a three-dimensional code has been developed for the study exclusively of the fluid inside the pharynx considering a non-Newtonian fluid. Three-dimensional geometries of the pharynx at ten different instants using high-order polynomials were generated. For any time range investigated, the shape of the pharynx was introduced into a Cartesian grid by using the technique of immersed boundaries and three-dimensional interpolations. The geometry evolved within this grid and the equations of fluid mechanics were numerically solved. The effect of the pharyngeal walls on the fluid was modeled from the theory of elastic membranes. Flow fields in terms of the axial velocity, pressure, shear rate and viscosity were obtained.
