Applications of computational fluid dynamics modelling in underground coal mines
Computational Fluid Dynamics or CFD has become a powerful tool to assist mining engineers and find solutions to these problems. CFD is a branch of fluid mechanics that embraces mathematics and numerical solution, by computational methods, of the governing equations which describe the motion of fluid flow, the Navier-Stokes equations, continuity and any additional conservation equations, such as energy or species concentrations. Nowadays high performance computers are used together with sophisticated CFD code such as ANSYS Fluent or CFX to perform the calculations required to model the interaction of liquids and gases. For mining related ventilation, health and safety problems, this would typically require visits to the mine site to discuss the problem with the ventilation engineers and examine relevant data to clarify any technical issues before developing the CFD models. The base CFD model has to be validated against field survey data before
