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…
Cavitation Rheology of Model Yield Stress Fluids Based on Carbopol
Hadi Mohammadigoushki, Kourosh Shoele
Measuring surface tension of yield stress fluids has remained a critical challenge due to limitations of the traditional tensiometry techniques. Here, we overcome those limits and…
Squirmer locomotion in a yield stress fluid
Patrick S. Eastham, Hadi Mohammadigoushki, Kourosh Shoele
An axisymmetric squirmer in a Bingham viscoplastic fluid is studied numerically to determine the effect of a yield stress environment on locomotion. The nonlinearity of the governi…
Mode Competition in a Plunging Foil with an Active Flap: A Multi-Scale Modal Analysis Approach
Tso-Kang Wang, Kourosh Shoele
The flow-induced flutter has a significant role in aircraft stability, renewable energy extraction, animal locomotion, among many other applications. While being a ubiquitous pheno…
Hybrid Wave/Current Energy Harvesting with a Flexible Piezoelectric Plate
Kourosh Shoele
We investigate the dynamics and energy production capability of a flexible piezoelectric plate submerged close to the free surface and exposed to incident head gravity waves and cu…
Axisymmetric Squirmers in Stokes Fluid with Nonuniform Viscosity
Patrick S. Eastham, Kourosh Shoele
The ciliary locomotion and feeding of an axisymmetric micro-swimmer in a complex fluid whose viscosity depends on nutrient concentration are investigated numerically. The micro-swi…
