Is ice cream a non-Newtonian fluid? It has been determined that the rheological behavior of an ice cream corresponds to a shear thinning non-Newtonian fluid [2,13]. Furthermore, this fluid acquires a viscoelastic behavior as the temperature decreases and the concentration of the crystals increases. What happens when the stress is removed from a non-Newtonian fluid? […]
