Summary of Results
Commercial software products, including VnetPC and Ventsim, are reliable tools that underground mines use to model their mine ventilation systems and predict the impacts of continued mining and ventilation system changes. However, VnetPC and Ventsim do not model areas of a mine that are caved and/or sealed where laminar or transitional airflow prevails. VnetPC is also limited to 2D modeling and cannot be used to model large 3D openings. Computational fluid dynamics (CFD) can be used for 3D modeling as well as the ventilated areas with turbulent airflow. The FLUENT code for CFD modeling has been applied previously on a limited scale for mine ventilation modeling.
Preliminary research has revealed existing success with CFD and FLUENT code, and literature searches and inquires carried out as part of the proposed research will likely result in other useful documented applications. The goal of this research and development effort would be to build on the existing work that has been accomplished.
