# Supercomputing; Concrete

This simulation depicts flow in a rheometer, as its rotating vane's blade begins to stir a suspension of particles. Colors represent the quadrant where the particles are initially positioned. Such simulations can be used to link measurements of torque and angular velocity to fluid properties like viscosity, and they also can provide insight into physical mechanisims that control particle dispersion and mixing.
