AbstractThe use of computational fluid dynamics (CFD) and lighting simulation software is becoming commonplace in building design. This study looks at a novel linkage between these two tools in the visualization of droplets or particles suspended in air. CFD is used to predict the distribution of the particles, which is then processed and passed to the lighting simulation tool. The mechanism for transforming CFD contaminant concentration predictions to a form suitable for visual simulation is explained in detail and an example presented which demonstrates this linkage. The CFD-visualisation simulations described in this paper have applications in both automotive and fire safety through the modelling of fog and smoke respectively. Historically, smoke and fog effects have been rendered in images with no attempt at modelling physical reality. The novelty of the work presented in this paper is that, for the first time, an attempt is made to model both the fluid mechanics and optical physics of small particles suspended in a primary fluid.
