Small-Scale Condensation Simulation on Complicated Surface

Abstract

Vapor condensation is a typical phenomenon in the nature, whose realistic simulation is of great significance to virtual reality, video effects, game entertainment, etc. Traditional physically-based methods failed to preserve the small-scale details during condensation. A novel hybrid framework combining smoothed particle hydrodynamics and adaptive fluid implicit particle method is proposed. The heat transfer of air is modeled with smoothed particle hydrodynamics, with phase transition controlled by relative humidity and dew point. The fluid implicit particle method is combined with an octree-based adaptive grid to achieve high-resolution details of small-scale drops. Finally, surface tension, adhesion and resistance are introduced to simulate the motion of drops on complicated surfaces realistically. It is demonstrated that proposed method provides plausible results of condensation on intricate surfaces efficiently through several experiments.
