Rheology print that page


change with the strain rate (or relative velocity of flow) and are called non-Newtonian fluids. Rheology generally accounts for the behavior of non-Newtonian fluids, by characterizing the minimum number of functions that are needed to relate stresses with rate of change of strains or strain

Food rheology print that page


There is a large body of literature on food rheology because the study of food rheology entails unique factors beyond an understanding of the basic rheological dynamics of the flow and deformation of matter. Food can be classified according to its rheological state, such as a solid , gel

Paste (rheology) print that page


In physics , a paste is a substance that behaves as a solid until a sufficiently large load or stress is applied, at which point it flows like a fluid . In rheological terms, a paste is an example of a Bingham plastic fluid . Pastes typically consist of a suspension of granular material

Viscosity print that page


stress is known as an ideal fluid or inviscid fluid . The study of flowing matter is known as rheology , which includes viscosity and related concepts. Contents 1 Etymology 2 Properties and behavior 2.1 Overview 2.2 Types of viscosity 3 Viscosity coefficients 4 Viscosity

Electroactive polymers print that page

The field of EAPs emerged back in 1880, when Wilhelm Roentgen designed an experiment in which he tested the effect of an electrical current on the mechanical properties of a rubber band . [ 2 ] The rubber band was fixed at one end and was attached to a mass at the other. It was then charged | 2011/5/23 14:17:42

Non-Newtonian fluid print that page


A non-Newtonian fluid is a fluid whose flow properties differ in any way from those of Newtonian fluids . Most commonly the viscosity of non-Newtonian fluids is not independent of shear rate or shear rate history. However, there are some non-Newtonian fluids with shear-independent viscosity

Dilatant print that page


A dilatant (also termed shear thickening ) material is one in which viscosity increases with the rate of shear strain . Such a shear thickening fluid , also known by the acronym STF , is an example of a non-Newtonian fluid . Comparison of the behavior of four types of fluids with shear

Rheometer print that page


require more parameters to be set and measured than is the case for a viscometer . It measures the rheology of the fluid. There are two distinctively different types of rheometers . Rheometers that control the applied shear stress or shear strain are called rotational or shear rheometers

Fluid dynamics print that page

In physics , fluid dynamics is a sub-discipline of fluid mechanics that deals with fluid flow —the natural science of fluids ( liquids and gases ) in motion. It has several subdisciplines itself, including aerodynamics (the study of air and other gases in motion) and hydrodynamics | 2011/10/1 3:59:26

Personal hygiene products mixing print that page

products due to complex formulations, stability, and performance requirements of each product. The rheology of the final and intermediate consumer products typically determines the mixing regime and the type of equipment required in the manufacturing process [1]. Relatively few consumer | 2011/6/30 22:52:40
