Three-dimensional numerical investigation on micro-meter droplet impact and penetration into the porous media with different velocities

Droplets impacting and penetration into porous media is commonly seen in natural engineering processes, which the kinetics capillary effect are of great importance to lateral spreading vertical penetration. In this study, a three-dimensional numerical simulation method was proposed study micro-meter droplet impact media. It found that both spread occur on millisecond timescale larger velocity will enhance but have little influence time depth. The direct can be applied predict actual status droplet-powder system further insight interaction.
