Abstract [en]

This work aims to numerically investigate how the heat and mass transfer boundary conditions at a droplet surface should be presented in order to fully represent the surrounding fluid flow. With aid of Computational Fluid Dynamics, a numerical study is carried out to investigate the validity of the heat and mass transfer analogy at the droplet surface. Natural convection in the air surrounding the droplet, arising from the heated surface below the droplet, is considered. The heat and mass transfer analogy needs to be deliberated when the evaporation is dominated by density differences rather than temperature differences and the numerical results show this transition in detail.
