Impact of capillary drops of complex fluids on a solid surface

CM Oishi, RL Thompson, FP Martins - Physics of Fluids, 2019 - pubs.aip.org
The drop impact on a solid surface is studied in the context of complex fluids that exhibit
viscoplastic, viscoelastic, and thixotropic behavior. The effects of rheology and surface …

The “avalanche effect” of an elasto-viscoplastic thixotropic material on an inclined plane

CM Oishi, FP Martins, RL Thompson - Journal of Non-Newtonian Fluid …, 2017 - Elsevier
The so-called avalanche effect is one of the fingerprints of thixotropic materials. This self-
reinforcing process where the decrease in viscosity, due to a rejuvenation process triggered …

Transient motions of elasto-viscoplastic thixotropic materials subjected to an imposed stress field and to stress-based free-surface boundary conditions

CM Oishi, RL Thompson, FP Martins - International Journal of Engineering …, 2016 - Elsevier
In the present work, we present an approach to handle transient flows of elasto-viscoplastic
thixotropic (EVPT) materials under the action of the gravity force field and subjected to free …
