Simulation of Water Condensation based on a Thermodynamic Approach

Abstract

We introduce a novel approach for physically based simulation of water drops on surfaces considering the thermodynamical laws like mixing temperature, specific heat capacity, water vapor, saturation, and additional material properties in an adiabatic environment. The algorithm is able to robustly handle huge scenes of complex closed and also non-closed objects defined as implicit surfaces and thus it is ideally suited for extending classical, wellknown fluid simulation models. A subset of thermodynamic rules based on a static grid is used. Other approaches use buoyant force and other equations based on motion, e. g. [HBSL03].
