Flow can be either shear, where fluid components shear past one another, or extensional, where fluid components either flow towards or away from each other. Most flow occurs via a shear mechanism, and this can be easily measured using a rotational rheometer. See more Shear flow can be described as several layers of fluid sliding over each other, with each upper layer moving faster than the layer below it. The … See more The most commonly seen type of non-Newtonian behavior is shear thinning, aka pseudoplastic flow. During shear thinning the viscosity of the … See more The majority of polymer-based materials and suspensions display only shear thinning, though some can also show behavior where … See more The different features of flow curves, which are illustrated in Figure 3, can be modeled using relatively simple equations. This approach allows the shape and curvature of flow … See more WebJul 15, 2024 · Rheology is the science of deformation and flow of matter. It is as important as any other discipline when studying adhesive systems. To ensure that adhesives and sealants function well during their application and end-use, the formulator must be able to control the flow properties of the product.
