✦ Synopsis

The longitudinal mixing produced in a liquid which Rows through the space between a stationary outer cylinder and a rotating cylindrical core can be interpreted as the result of an apparent longitudinal diffusivity.

For various dimensions and rotor speeds the value of the diffusion coefficient has been measured by means of the frequency response analysis.
