Abstract. In this work, mass-transfer coefficients of a cross-corrugated plate have been determined by the limiting-current technique. A simple Microsoft Excel spreadsheet has been created, which allows students to correlate data. Students will be able to calculate the mass-transfer coefficient of different processes, for example, cross-flow membrane filtration processes or membrane reactors. The possibility of using the spreadsheet with different correlations and to discriminate between them is also validated by comparing the model results with published experimental data available in the recent literature. It is possible as well to study the influence of different turbulence promoters on the flow.
