WebHigbie’s penetration theory There are several theories concerned with mass transfer across a phase boundary. One of the most widely used is Whitman s two- film theory in which the resistance to transfer in each phase is regarded as being located in two thin films, one on …
WebThe film theory has been extensively applied to describe the mass transfer in systems in which fluid phases are present. The theory considers that the resistance to mass transfer in a given turbulent fluid phase is present in a thin layer adjacent to the interface that is called a film (Seader et al., 2011 ).
