Mass transfer to rotating disks and rotating rings in laminar, transition and fully-developed turbulent flow
Abstract
Experimental data and theoretical calculations are presented for the mass-transfer rate to rotating disks and rotating rings when laminar, transition, and fully-developed turbulent flow exist upon different portions of the surface. Good agreement of data and the model is obtained for rotating disks and relatively thick rotating rings. Results of the calculations for thin rings generally exceed the experimental data measured in transition and turbulent flow. A form in terms of the third power of the dimensionless axial position for the eddy diffusivity is used to fit the data. No improvement is noticed with a form involving both the third and the fourth powers of the dimensionless axial position.
