Summary

Combined heat and mass transfer processes that occur when water evaporates from a flowing film have been investigated. A fiber-optic holographic interferometer was used to measure the local heat and mass transfer coefficients from the air-liquid interface, and a set of thermocouples and a dewpoint hygrometer were used to measure the average heat and mass transfer rates in the system, first, without utilizing any enhancement techniques, then with 2 mm glass rods used to disturb the liquid film flow, which also disturbed the flow of the air stream.
