The project C1 is devoted to the numerical simulation of drop impact onto hot surfaces. The drop impact at a macroscale is simulated using a solver within the OpenFOAM package, in which the two-phase flow is described using the Volume-of-Fluid (VOF) method accounting for evaporation at the liquid-vapor interface. The detailed model for the description of evaporation in the vicinity of the three-phase contact line is coupled with the VOF-model using correlations. In the third funding period, the interaction of several impacting drops will be simulated in a wide range of parameters.

项目C1致力于对热表面上的液滴冲击进行数值模拟。使用OpenFOAM软件包中的求解器模拟宏观尺度下的跌落冲击，其中使用液体体积（VOF）方法描述两相流，该方法考虑了液-气界面处的蒸发。描述三相接触线附近蒸发的详细模型与VOF模型相结合，使用相关性。在第三个供资期内，将在广泛的参数范围内模拟几个撞击液滴的相互作用。
