Investigation of the numerical simulation of debris flow fluid with concern of phase transition

Frontiers in Earth Science, 2022
From a variety of yield stress fluid models, an elastoviscoplastic Herschel-Bulkley (EVPHB) model written in 3D is selected and coupled with a Finite Element Method with Lagrangian Integration Points (FEMLIP) to solve boundary value problems with large ...

Modelling laminar transport phenomena in a Casson rheological fluid from an isothermal sphere with partial slip in a non-Darcy porous medium [PDF]

Theoretical and Applied Mechanics, 2013
The flow and heat transfer of Casson fluid from a permeable isothermal sphere in the presence of slip condition in a non-Darcy porous medium is analyzed. The sphere surface is maintained at a constant temperature. The boundary layer conservation

Shear-induced sedimentation in yield stress fluids [PDF]

, 2012
Stability of coarse particles against gravity is an important issue in dense suspensions (fresh concrete, foodstuff, etc.). On the one hand, it is known that they are stable at rest when the interstitial paste has a high enough yield stress; on the other

Properties and mechanism of ionic liquid/silicone oil based magnetorheological fluids

International Journal of Smart and Nano Materials, 2022
A magnetorheological fluid (MRF) is a smart composite suspension composed of nonmagnetic liquid and soft magnetic particles. Carrier fluids can considerably influence the performance of MRFs; therefore, to investigate the effect of carrier fluids on MRFs,

Size effects in dislocation depinning models for plastic yield

, 2013
Typically, the plastic yield stress of a sample is determined from a stress-strain curve by defining a yield strain and reading off the stress required to attain it.

Conditional QTL Analysis and Fine Mapping for Thousand-Kernel Weight in Common Wheat

Plants
To elucidate the genetic basis of thousand-kernel weight (TKW) related to fundamental traits such as kernel length (KL), kernel width (KW), and kernel diameter ratio (KDR) at the individual quantitative trait loci (QTL) level, both unconditional QTL ...

Rheological Characterization of Yield-Stress Materials: Flow Pattern and Apparent Wall Slip

Applied Rheology, 2015
An experimental and numerical investigation of the rotational rheometry of yield-stress materials is performed, using waterbased Carbopol dispersions. The flow and fluid characterization in different rheometer geometries, namely the smooth Couette, the ...

How quarry waste limestone filler affects the rheological behavior of cement-based materials

Applied Rheology, 2021
The main objective of this work is to highlight experimentally the effect of quarry waste limestone fillers (LF) on the rheological properties of concrete. All mixtures were made with water-to-cement ratio (W/C) of 0.50.
