What is the main objective of Rheopexy?
Rheopecty or rheopexy is the rare property of some non-Newtonian fluids to show a time-dependent increase in viscosity (time-dependent viscosity); the longer the fluid undergoes shearing force, the higher its viscosity. Rheopectic fluids, such as some lubricants, thicken or solidify when shaken.
What is anti thixotropy?
The term anti-thixotropy is used when the apparent viscosity is an increasing function of the duration of flow and when, as with thixotropy, the body recovers its initial state after a long enough rest.
What does thixotropy mean?
Definition of thixotropy : the property of various gels of becoming fluid when disturbed (as by shaking) … says that blood liquefaction can be explained in terms of a phenomenon called thixotropy.
What are rheopectic and thixotropic fluids?
The key difference between thixotropic and rheopectic fluids is that in thixotropic fluids, the viscosity of the fluid decreases with stress over time whereas, in rheopectic fluids, the viscosity of the fluid increases with stress over time. Fluids are liquid or gaseous substances that have a viscosity.
What is thixotropy and negative Thixotrophy?
Negative thixotropy, also called antithixotropy, is the effect of a flow-induced increase in viscosity that has been observed for many polymer solutions. Here, a simple quantitative model describing the time dependence of the shear stress or viscosity is presented.
How does a thixotropy work?
‘Thixotropy’ is shear thinning property; when an alloy is sheared it thins, but when it is allowed to stand it thickens again. This behavior is associated with the breakup of agglomerates of solid particles under shear and their reformation when the shear is removed.
What is thixotropic behavior?
In rheology thixotropic behavior is defined as time-dependent behavior. It means a reduction of the structural strength during a constant shear load phase and a more or less rapid but complete regeneration of the structure during the subsequent rest phase.
What do flowers mean to you?
