Mass transfer to a rotating fluid: Part I. Transport from a stationary disk to a fluid in bödewadt flow

Solutions are developed for mass transfer between a fluid undergoing solid body rotation and a coaxial disk which is located on a stationary infinite surface. The fluid mechanics corresponds to a laminar Bödewadt boundary layer. The overall mass transfer is dominated by the outer portion of the disk, a result of the high transfer rate associated with a leading edge. The concentration field near the axis of rotation extends to great axial distances as a long narrow plume. Approximate analytical solutions are given for each of these regions, and a numerical solution is provided for the entire concentration field.
