WebNov 14, 2024 · Rheology is the science that describes deformation and flow behaviors of materials. Rheology models summarize the physical responses (rheological parameters) under a certain deformation stress or a flow driving force. These parameters (1) reflect processability of crude, or semi-processed or processed food materials, (2) determine … WebThe flow behavior index, , is determined as the gradient of a plot of versus on logarithmic coordinates. In the case of the value of is less than unity, it is called pseudo-plastic fluids. This type of behavior is widely encountered in polymer solutions or fine solid particle … Newtonian fluids, such as water or oil, are characterized by a viscosity (i.e. the … In Eqs.
