In polymer systems such as polymer melts and solutions, shear thinning is caused by the disentanglement of polymer chains during flow. At rest, high molecular weight polymers are …

A steady, one-dimensional flow of an incompressible, pseudoplastic fluid is investigated. It is convenient to choose a cylindrical coordinate system with the notation as shown in Fig. 14.10.

Mar 2, 2024 · Plastic Flow vs. Pseudoplastic Flow: What's the Difference? Plastic flow occurs when a material deforms permanently under stress after exceeding the yield point, while …

Plastic flow involves the transition from solid-like behavior to liquid-like behavior once a yield stress is exceeded, while pseudoplastic flow is characterized by a continuous decrease in …

Mar 15, 2022 · Figure 3 provides an illustration of a non-Newtonian pipe flow system from a mining application as modeled in FluidFlow. The system includes two pumps in parallel …

The terms “shear-thinning” and “pseudoplastic flow behavior” are synonyms. This behavior is characterized by decreasing viscosity with increasing shear rates, caused by the samples …

Pseudoplastic flow, often called shear-thinning, describes the behavior of fluids whose viscosity decreases as the shear rate increases. This means the fluid becomes easier to flow as it is …

Jul 2, 2025 · Newtonian (n = 1) and pseudoplastic (n = 0.8, 0.5) fluid flow over a rectangular cylinder placed near a plane wall (gap ratio G/a = 0.25 and 1) is studied numerically using …

Linear polymers in solution exhibit pseudoplastic flow. A large number of pharmaceutical products, including natural and synthetic gums (e.g., liquid dispersions of tragacanth, sodium …

A decreasing viscosity with an increase of shear rate is called shear thinning or pseudoplastic flow (Figure 46.12a). An increasing viscosity with an increase of shear rate is called shear …
