WebApr 24, 2024 · Rheological parameters for yogurt samples were measured using the Herschel–Bulkley model to determine flow behavior. The determination coefficient (R 2) for 1:1, 2:1, 1:2, and the control S samples ranged from 0.990 to 0.999, which was an acceptable fit for the flow curves .

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 response to an applied force. Rheology is a branch of physics, and it is the science that … 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 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 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.
