Define thixotropy
Thixotropy is a time-dependent shear thinning property. Certain gels or fluids that are thick or viscous under static conditions will flow (become thinner, less viscous) over time when shaken, agitated, shear-stressed, or otherwise stressed (time-dependent viscosity). They then take a fixed time to return to a more viscous state. Some non-Newtonian pseudoplastic fluids show a time-dependent chang… WebThixotropy has been proposed as a scientific explanation of blood liquefaction miracles such as that of Saint Januarius in Naples. [2] Other examples of thixotropic fluids are …

WebIn rheology, shear thinning is the non-Newtonian behavior of fluids whose viscosity decreases under shear strain.It is sometimes considered synonymous for pseudo-plastic behaviour, and is usually defined as excluding time-dependent effects, such as thixotropy.Shear thinning is the most common type of non-Newtonian behavior of … WebPublisher Summary. This chapter presents the measurement and occurrence of thixotropy and dilatancy. The concept of thixotropy arose in the study of certain colloidal dispersions. These were capable of stable existence as solid materials with a low modulus of elasticity when under a low shearing stress such as a few inches of gravitational head.
