Magnetorheological (MR) fluids are field-responsive suspensions of magnetizable particles which rheological properties can be dramatically altered by applying external magnetic fields (Phulé and Ginder 1998). Under the presence of a magnetic field, anisotropic chainlike structures result from field-induced particle magnetization as a consequence of the permeability mismatch between particle and...

A range of rheological and morphological techniques, contributed by nine laboratories, are used to characterise the flow behaviour in a model long fiber reinforced thermoplastic system. It is concluded that in capillary rheometry, the pressure drop fluctuations that typifl the flow arise from two mechanisms, that of local fiber fraction inhomogeneity passing through the die, and the instability...

Semi-solid aluminium alloy processing (SSM) has advanced into a more mature process with many applications. The current paper aims to investigate the in-process behaviour of production slurry using an engineering approach estimate properties. A method assess rheological properties semi-solid metal was tested and found capable producing meaningful measurements. foundations this were use Rushton ...

The tensile strength of tablets compressed from binary mixtures is in general not linearly related to the strength of tablets prepared from single materials; in many cases it shows a decreased tensile strength relative to interpolation. The materials used in this study, sodium chloride and pregelatinised starch, are both plastically deforming materials, but have a different densification and re...

Abstract: Rheological behaviour of fluids in mixing systems was studied using a simplified approach in shear rate calculation. The efficiency of this approach is investigated from Newtonian and non-Newtonian fluids, exploring also the geometry of mixing systems. Results are favourably compared with those obtained from previous published works. It is shown that this approach does not require the...

Highly filled polymeric suspensions, such as those involved in Powder Injection Moulding (PIM), exhibit complex rheological behaviour. A detailed understanding of the rheology of these suspensions is prerequisite for their optimum and safe processing. In present paper, rheological behaviour of highly filled WC-Co compounds during capillary flow was studied with emphasis on apparent slip. Contri...

Abstract Water-soluble polymers have been shown to improve the flow rigidity and water retention ability of highly-branched (flocculated) polydisperse water-suspended MFC, thereby also modifying controlling their rheological behaviour. The addition hydroxyethyl (HEC) carboxymethyl (CMC) celluloses different content (5–10–20 w/w%), molecular weights (M W , 90.000–1.300.000 g/mol) degrees substit...

This article reviews what has been published on the rheology of worm-like micellar fluids (WLMFs). It is written primarily for those interested in continuum (non-Newtonian fluid) mechanics: it covers the bulk rheological behaviour of typical WLMFs and rheological equations of state (REoS) that reflect this bulk behaviour; it also covers molecular dynamics and Brownian dynamics models that aim t...
