Time- and rate-dependent material functions in Non-Newtonian fluids in response to different deformation fields pose a challenge in integrating different constitutive models into conventional computational fluid dynamic platforms. Considering their...

Pushing the bounds of public relations theory and research, we explore how institutional texts have produced and reified stigmas around gender transgression and how these texts are bound up in moments of activism and resistance. We considered how different discursive and material functions get “stuck” together by way of texts and how this sticking depends on a history of association and institutionalization. Activism presents opportunities to challenge institutional and structural stickiness, and we argue that public relations can challenge the affective assemblages that comprise and perpetuate these systems, unsettling the historical discourses that have governed institutions by establishing new communicative possibilities.

Abstract The vane geometry with a large gap is used to determine the Newtonian, non-Newtonian and viscoelastic properties of complex fluids. We show that when this geometry is carefully characterized, it can be used for precise rheometry. A novel effective cylinder approximation is used to obtain the shear rate and shear stress factors. The effective radius is found to be close to the height of the triangle formed by joining the tips of adjacent blades. This result differs significantly from that of previous work. Flow visualization has been used to confirm that the stream lines bend towards the centre between the blades. These factors can be used to determine the flow curves of non-Newtonian liquids, using Krieger’s power law expansion. The standard procedure for using the vane to determine the yield stress is also carefully investigated and alternative procedures are suggested.
