Spinning Rods: Experiment \& Theory*

Mixing and transport properties of the fluid motion induced by a slender rod attached to a plane sweeping out a cone are examined in a table- top experiment. This experiment is used to validate an exact solution for the motion of a spheroid sweeping out a double cone in free space and an asymptotic solution for a slender body attached to a plane. Validation of the theory is used to examine mixing and transport of the same experiment on the microscale.
