My work in stokesian Dynamics

Hi everyone ! I like to explain that what I have to do with Stokesian Dynamics. After working in this field for a year I came to know about the various places where this can be applied for example biofluidics (to know the stress on the blood vessels, cell transfer), carbonnanotubes etc. The most interesting thing about this tool is that it can be easily scaled for a nano as well as a macro system as the equations solved here are dimensionless in nature. What is important here is that we are mainly concerned with particle motion rather then that of  fluid, present inside the fluid (remember we are dealing with suspensions which constitutes of fluid and solid rigid spherical particles). This kind of modeling is discrete in nature.

Relating the force and velocity of particles through constants depending on the configuration of system forms the heart of Stokesian Dynamics. Brady, Bossis, Durlosky mainly used this to simulate suspension with great precision and accuracy. Anyways what I am trying to do is to simulate dilute suspension inside the rotating horizontal cylinder made of spherical particles.
