Thermo-hydrodynamic modelling of evaporation-related phenomena


Abstract : The ULB-TIPs department is a partner in several fluid-physics research programmes of the European Space Agency, and moreover participates in the Interuniversity Attraction Poles project MicroMAST (Multiscale Applications of Surface Tension: Microfluidics and Micromanipulation). In this framework, TIPs develops applied mathematical models and numerical codes both for interpreting experiments and developing predictive tools. Several tasks in the mentioned projects involve evaporation and the flows it induces in the liquid and gas phases, such flows influencing back the evaporation rates. A typical setup of special importance here is a sessile drop on a solid substrate evaporating into the ambient air, which is a topic of active research nowadays, due to many applications in drying or deposition techniques (see e.g. the “coffee-stain” effect, used to produce self-organized nanoparticle deposition patterns). Other examples are plates partly immersed in an evaporating liquid (important e.g. for the dip-coating technique), evaporating menisci (relevant in many imbibitions processes), ... The proposed PhD candidate is expected to develop common strategies to tackle such evaporation-related problems, and to become a “hard-core” numericist in the corresponding area, both developing from scratch his own codes (using any programming language) and mastering existing commercial software (COMSOL Multiphysics, or FLUENT).
