Drag and Yielding of Rotating Bodies in Yield-Stress Fluids
Farshad Nazari, Akash Mittal, Kourosh Shoele +1
We investigate the settling dynamics of rotating objects in a yield stress fluid by combining controlled experiments with numerical simulations. Experiments were conducted using cy…

Helical Locomotion in Yield Stress Fluids
Farshad Nazari Kourosh Shoele, Hadi Mohammadigoushki
We report three stages for locomotion of a helical swimmer in yield stress fluids. In the first stage, the swimmer must overcome material's yield strain to generate rotational moti…

Flow of a two-dimensional liquid foam: Impact of surfactant type and boundary conditions
Farshad Nazari, Andrei Potanin, Hadi Mohammadigoushki
In this study, we experimentally investigate the rheological and flow behavior of two-dimensional (2D) monodisperse aqueous foams, sheared between parallel plates using a custom-ma…
