Reviving the Suspension Balance Model
Mu Wang, Tingtao Zhou, John F. Brady
The Suspension Balance Model (SBM) [J. Fluid Mech. \textbf{275}, 157 (1994)] for two-phase flows uses the momentum balance of the particle phase as a closure for the particle flux,…
Nonmonotonic diffusion in sheared active suspensions of squirmers
Zhouyang Ge, John F. Brady, Gwynn J. Elfring
We investigate how shear influences the dynamics of active particles in dilute to concentrated suspensions. Using apolar active suspensions of squirmers as model systems, we show h…
Hydrodynamic interactions destroy motility-induced phase separation in active suspensions
Tingtao Zhou, John F. Brady
Motility-Induced Phase Separation (MIPS) is a distinctive phenomenon in active matter that arises from its inherent non-equilibrium nature. Despite recent progress in understanding…
Active doping controls the mode of failure in dense colloidal gels
Tingtao Zhou, John F. Brady
Mechanical properties of disordered materials are governed by their underlying free energy landscape. In contrast to external fields, embedding a small fraction of active particles…
