RÉSUMÉ
An experimental and numerical study of thermal Marangoni - natural convection in shallow liquid layers was carried out for a range of temperature differences and layer depths. Particle Image Velocimetry (PIV) was used to obtain the flow patterns and velocity vectors. The experimental results were compared to numerical models created using FLUENT V6. Both results are in good agreement. The liquid free surface profile due to the presence of the menisci is shown to be critical for good quantitative validation. The layer depths are also proven to be shallow enough for Marangoni convection to dominate over buoyancy under normal gravity conditions.
