Flow rheology

WebNov 25, 2024 · The study of flow or deformation of materials when subjected to stress is called “Rheology”. In the case of solids, the material deforms elastically when stress is applied. In the case of liquids/fluids, when stress is applied, the material initiates flow, and the energy utilized disperses within the fluid as heat. WebDec 17, 2024 · The rheology of slurries consisting of less-than-or-equal-to 2-mm sediment from a natural debris flow deposit was measured using a wide-gap concentric-cylinder viscometer.

WebJan 1, 2014 · The rheology of sediment gravity flows falls into two main classes of flow behavior that are fundamentally different and which difference is often reflected in the final deposit. The first class is characterized by fluidal behavior similar to Newtonian fluid, where shear stress is linearly related to strain according to WebDec 15, 2013 · 1. Introduction. Morphological dimensions of lava flows are commonly used in planetary sciences to infer the rheological properties (viscosity, yield strength) of the erupted material, which are in turn used to estimate the silica content of the lava. Simple isothermal models of lava flow emplacement have been used to extract these properties ...
