Abstract
A method and apparatus for the transfer of mass with the aid of rotating surfaces. The fluid with which an exchange or transfer is to be made is introduced in parallel in one or more gaps or channels defined between the rotating surfaces. Rotation of the surfaces causes the major part of the fluid flow to pass through a rotating, flow mechanical boundary layer adjacent the rotating transfer surface in laminar or turbulent flow.
