Experimental and/or numerical study of the vapour cloud surrounding evaporating droplets

Abstract : A simple sessile droplet evaporating into air is a very common event which has many industrial applications such as spray drying, DNA handling, coating, ink-jet printing, dish-washers... The total evaporation time of such a droplet is heavily influenced by the shape of the vapour cloud surrounding the drop. At ULB-TIPs we have developed an interferometric technique capable of measuring the vapour cloud surrounding such a drop for the first time (for an example video see: http://tiny.cc/zr84tw). The candidate will be trained how to perform such high-precision interferometric measurements and how to perform its image processing. The candidate will then apply this technique to different configurations (different thermal properties, different vapour weights, ...) in order to assess their influence. In parallel, a numerical code should be developed (possibly with COMSOL Multiphysics) to simulate the vapour cloud configuration and compare it to the experimental results. For this position no specific optics or image processing knowledge is required.
