Photometrical rheology
Rheology is a branch of physics, and it is the science that deals with the deformation and flow of materials, both solids and liquids. The term rheology was coined by Eugene C. Bingham, a professor at Lafayette College, in 1920, from a suggestion by a colleague, Markus Reiner. See more Rheology is the study of the flow of matter, primarily in a fluid (liquid or gas) state, but also as "soft solids" or solids under conditions in which they respond with plastic flow rather than deforming elastically in … See more In practice, rheology is principally concerned with extending continuum mechanics to characterize the flow of materials that exhibit a combination of elastic, viscous and plastic behavior by properly combining elasticity and (Newtonian See more Rheometers are instruments used to characterize the rheological properties of materials, typically fluids that are melts or solution. These instruments impose a specific stress field or deformation to the fluid, and monitor the resultant deformation or … See more A rheologist is an interdisciplinary scientist or engineer who studies the flow of complex liquids or the deformation of soft solids. It is not a primary degree subject; there is no … See more • Fluid and solid character are relevant at long times: We consider the application of a constant stress (a so-called creep experiment): See more Deborah number On one end of the spectrum we have an inviscid or a simple Newtonian fluid and on the other end, a rigid solid; thus the behavior of all materials fall somewhere in between these two ends. The difference in material behavior is … See more Rheology has applications in materials science, engineering, geophysics, physiology, human biology and pharmaceutics.

The magnitude of time-dependent change is correlated to … WebRheology is a general term referring to the science of studying flow and deformation of materials. Viscosity is defined as the resistance of a liquid to flow. For example, ketchup has a higher viscosity than water. An understanding of rheology and viscosity is essential to processing of polymers and coating.
WebRelative measuring geometries are used with rheometers to characterize a wide range of samples. A relative measuring geometry delivers values which are relative values (as opposed to absolute values). Relative values are specific to the geometry used. With relative geometries; results are only comparable when using the same geometry.
