The presumption that the solid-liquid transition occurs at a single invariant stress ignores that the microstructure may adjust dynamically when flow begins.BonnWZIDanielWZIDennWZIMortonWZIM.WZIEBSCO_AspScienceD. Bonn,M.D. Morton.Yield stress fluids slowly yield to analysis.Science. 2009...
Yield stress fluids slowly yield to analysis. We are surrounded in everyday life by yield stress fluids: materials that behave as solids under small stresses but flow like liquids beyond a critical str... Daniel,Bonn,Morton,... - 《Science》 被引量: 152发表: 2009年 Yield Stress Fluids ...
We consider a displacement of several yield-stress fluids in a Hele-Shaw cell. The topic is relevant to the development of a model for the flow of multiple phases inside a narrow fracture with application to hydraulically fracturing a hydrocarbon-bearing underground formation. Existing models for ...
Yield Stress In subject area: Mathematics The static yield stress is the minimum stress required to cause the fluid to flow. From: Studies in Interface Science, 2005 About this pageSet alert Also in subject area: EngineeringDiscover other topics ...
Drilling fluids are usually formulated as viscoplastic materials to inhibit flow below the fluid yield stress, precluding cuttings to drop to the well bottom under static conditions. On the other hand, some theoretical works in the literature [1], [2] have demonstrated that the non-transmission ...
master curve of the yield stressCheng et al . (2010)'s experimental results for the static yield stress of giant electrorheological (GER) fluids over the full range of electric field strengths were reanalyzed by applying Seo's scaling function which could include both the polarization and the ...
In this paper a new method is presented in order to determine the pore size distribution in a porous medium. This original technique uses the rheological properties of some non-Newtonian yield stress fluids flowing through the porous sample. This technique is based on the capillary bundle model ...
Yield stress analysis of 1D calcium and titanium precipitate-based giant electrorheological fluids 来自 国家科技图书文献中心 喜欢 0 阅读量: 49 作者:YD Liu,Y Cheng,G Xu,HJ Choi 摘要: 1D calcium and titanium composite nanorods synthesized were applied as electrorheological (ER) active materials with...
We report on direct ink writing of a model yield-stress fluid and focus on the printability of the first layer, the one in contact with the supporting substrate. We observe a diversity of deposition morphologies that depends on a limited set of operation
