Résumé

So far, Marangoni convection has not been satisfactorily explained. This work, completing two previous studies, gives the basic mechanism explaining this effect. Some typical case studies, where Marangoni convection occurs, are regarded in the light of this new theory. The TPT is further used to model a pseudo-Marangoni cell with an ammonia/water absorption process. Special attention has been paid to the application of this theory to the cell gas-liquid interface conditions. All modelling results confirm the Marangoni convection basic mechanism explanation, which is general. The work emphasizes that TPT is a powerful tool in refined qualitative/quantitative binary two-phase local interaction analysis. Here, it was essential to develop an explanation for Marangoni convection.
