Developing Models and Simulations of Magnetically-Driven Flows of Dilute Suspensions of Magnetite Particles

Ischemic strokes, which are caused by blockage of blood flow due to the blood clots, are one the most common types of strokes.  The ischemic stroke causes the shortage of oxygen to the brain due to the thrombus (blood clot). Due to the bleeding complications, which are caused by increasing the plasmin in the body, the usage of large doses of thrombolytic is not possible.

In the case of a fully occluded artery, the drug is only transferred for a short distance into the blocked vessel by convection mechanism, and transport of the drug to longer length scale is diffusion-limited.  In this study, we aim to model and simulate the drug delivery to a fully occluded blood vessel using a magneto-rheological fluid that is caused by a rotary magnetic field with a gradient.

Rheology of soft particle glasses

Soft particle pastes have been used in food and cosmetics processing, surface coating, construction, and drilling industry.  Depending on the timescale of a given process, these systems can show solid-like and liquid-like behaviors.  Previously in our group, a three-dimensional micromechanical model for the soft particle pastes was developed.  In this research, we aim to understand the effect of attractive forces between the deformable particles on the rheological properties of these systems by developing a new model that includes attractive interactions between the particles.
