Mass transfer to a plane below a rotating disk at high Schmidt numbers

Authors


Abstract

The Lighthill transformation is used to determine the rate of mass transfer at high Schmidt numbers to a disk imbedded in a stationary plane below a rotating disk. This diffusion-layer solution breaks down near the center and leading edge of the mass-transfer disk. Solutions in these regions are reported, and a uniformly valid composite solution for the local Nusselt number is determined along with an expression for the average mass-transfer rate to the disk.
