Paper Abstract

Contamination modeling provides important insights into the transport mechanisms among sources, sinks, and sensitive surfaces. It is an indispensable tool in the discipline of contamination control and is often used to predict the outcome of a contamination event. As problems in contamination control can span multiple flow regimes and types of contaminants, it is important to develop such capability using a versatile tool. The Open source Field Operation and Manipulation (OpenFOAM) open source software is a customizable numerical solver that provides a solid foundation for the development of contamination modeling capability. It is a computational fluid dynamics tool that over the years has added particle tracing capabilities rendering it extremely versatile for transport modeling. In this paper, we show how OpenFOAM can be modified for modeling particulates settling under a flow field and molecular flow under the space vacuum environment. We show how new boundaries are created to simulate sources and vents and the accumulation of contaminants on surfaces over time. Finally, we discuss performance of OpenFOAM using our load-balanced Atlas Cluster on a computational intensive simulation.
