Non-local Rheology Tests in Intermediate Flows

This report provides a summary of the results to date.

Research Plan & Summary

1. Test the applicability of two non-local theoretical models.
2. Obtaining a quantitative connection between the two geometries by measuring the non-local measurements of velocity, shear and stress at higher inertial numbers.
3. Using the avalanche geometry as an alternative to the annular shear cell, to obtain yield ratio µs for both sets of particles.

Cambridge in January 2018 for two weeks. The goals of this 1-year collaborative project were:

NCSU in November 2017 for two weeks, while Zhu Tang travelled to the University of NC State. The collaboration grant involved two reciprocal visits; Amalia Thomas visited (intermediate flow, higher inertial number I) than was available in the annular Couette cell at nonlocal rheologies [Kamrin and Koval 2012, Bouzid et al. 2013] using a faster flow.
