A method for the numerical simulation of three-dimensional evaporation processes is applied to the evaporation process of isooctane droplets under slow inflow conditions and to the evaporation of a water droplet tandem in quiescent air. The method is a thermodynamically consistent numerical framework and was developed for the requirements of the evaporation of hot, liquid droplets. It is implemented into the in-house multi-phase code FS3D, which uses a Direct Numerical Simulation approach based on the Volume-of-Fluid method. Three different simulation cases are presented for the isooctane droplets and their results are in good agreement with literature correlations. The influence of the near drop neighbourhood can be observed in the simulation of the water droplet tandem.



The research was carried out in the framework of the industrial collective research programme (IGF no. 19320 N/2). It was supported by the Federal Ministry for Economic Affairs and Energy (BMWi) through the AiF (German Federation of Industrial Research Associations eV) based on a decision taken by the German Bundestag. We thank the High Performance Computing Centre Stuttgart (HLRS) for support and supply of computational time on the Cray XC40 platform under Grant No. FS3D/11142.
