Rheological inferences with uncertainty quantification
Fitting meaningful model parameters to relevant data is a valuable tool for inferring microstructural information from rheology. In this work, we focus on the asymptotically-nonlinear medium-amplitude oscillatory shear (MAOS) data, the next systematic step after small-amplitude oscillatory shear …

Engineering applications of electro-rheological fluids
The use of electro-rheological (ER) fluids is relatively new in engineering applications. ER fluids can change from liquid to solid-like gel under an electrical field, and this change takes place within milliseconds. The change is reversible once the electrical field is removed. This thesis is an …

Rheological Behavior of Coal-Water Slurries
<p>The rheological behavior of coal-water slurries was stud ied, using a Brookfield Rheolog viscometer with a thermosel system to maintain constant temperature. The coal used for making up the slurries was Sarpy Creek subbituminous coal from Montana. The effect of particle size, slurry concen …

Rheological Study of Concentrated Silica Suspensions
<p>Concentrated suspensions of silica in water were investigated using a rotational viscometer and a Zeta-Meter. The viscometric data was analyzed for shear dependence, solid concentration dependence and pH dependence. The data for electrophoretic mobility was analyzed for pH dependence.</p><p>The …

Rheological investigations of debris flow materials
A 2.0 m diameter viscometer/rheometer was designed, constructed, and used to test the behaviour of coarse grained debris flow materials. A 1/5 scale model was also constructed and used to test fluid-only and grain-fluid mixtures. The 30° inverted cone-and-plate viscometric system produced results …

Molecularly thin rheological and contact interfaces
A molecularly thin lubricant layer (of the order of 1-2 nanometers thick) has been shown to provide bearing forces at the interface between contacting solid surfaces under light loads and high shear rates. This phenomenon is important, for example, in the head-disk contact in magnetic storage hard …

The Stability Properties of Some Rheological Flows
The stability of wall driven and thermally driven cavity flow is investigated for a wide range of viscous and viscoelastic fluids. The effect of inertia, elasticity, temperature gradients, viscous heating and Biot boundary conditions are of particular interest. Both destabilisation and bifurcation …

Broadband Rheological Characterisation of Soft Functional Materials
Conventional bulk rheology presents a well-established technique for the mechanical characterisation of soft materials, ranging from liquid suspensions and emulsions to tenuous or even stiff gels. Probing the internal microstructure and understanding the relaxation of such materials has always been …

Rheological Study of a Direct Liquefaction Feed Slurry
<p>A rheological study was made of a liquefaction startup- feed slurry. The slurry consisted of North Dakota lignite sized to 70% less then 200 mesh and a carrier solvent of an thracene oil. The rheological behavior of the slurries, o with coal concentrations of 0 to 40% at 40 C, was shown to be …

Rheological Properties of Soybean and Soybean-Solute Systems
In developing countries, the high cost of cows milk protein and lack of refrigeration are two problems which contribute to protein deficiencies among the young. Concentrated intermediate moisture soybean beverages, if successfully developed, would represent a partial solution to both the above …
