Mass transfer relations for transpiration evaporation experiments. (English) Zbl 1188.76264
Summary: Transpiration evaporation experiments are often used to study evaporation kinetics from liquids or melts. The mass transport of volatile species in a transpiration experiment depends among others on the flow conditions of the carrier gas in the tube and on the geometrical configuration.
For a transpiration test set-up, CFD modelling showed to be an excellent tool to predict the mass transport of volatile species into a carrier gas and to understand the fluid dynamics in the gas phase and distribution of volatile species in this phase. Relatively simple mass transport relations were obtained for a fixed geometry of the transpiration test set-up. These relations proved to be also applicable for different volatile species and different temperature ranges.
