| Abstract (English): | Computational fluid dynamics (CFD) modeling involves the creation of a computation domain called a mesh or grid to solve the equations defining the physics of fluid flow. This process often comprises the majority of time spent in modeling efforts. In a project sponsored by the U.S. National Institute for Occupational Safety and Health (NIOSH), researchers at the Colorado School of Mines used an innovative meshing approach, allowing easy adaptation of the CFD model to adjust to a variety of longwall bleeder-ventilated and progressively sealed (often referred to as bleederless in the United States) mining geometries, with gob porosity and permeability scalable over a wide range. This paper presents the methodology of the meshing and scaling approach along with recommendations for using CFD modeling in longwall gob ventilation applications. The new meshing technique was utilized to evaluate the function of a back return in a progressively sealed gob and a bleeder-ventilated gob. [ABSTRACT FROM AUTHOR] |
| Abstract (Spanish): | El modelamiento de la dinámica de fluidos computacional (CFD por sus siglas en inglés) implica la creación de un dominio de cálculo llamado malla o rejilla para resolver las ecuaciones que definen la física del flujo de fluidos. Este proceso comprende a menudo emplear la mayor parte del tiempo en esfuerzos de modelamiento. En un proyecto patrocinado por el Instituto Nacional de Seguridad y Salud Ocupacional (NIOSH), los investigadores de la Escuela de Minas de Colorado utilizaron un enfoque innovador de mallas, el cual permite una fácil adaptación del modelo CFD para adaptarse a una variedad de geometrías de minado de tajos largos ventilados por canales (bleeders) y progresivamente sellados (referidos a menudo como bleederless en los Estados Unidos), con la porosidad y la permeabilidad de la cámara escalables en un amplio intervalo. En este trabajo se presenta la metodología del enfoque de enmallado y escalado junto con las recomendaciones para el uso de modelos CFD en aplicaciones de ventilación para las cámaras en tajos largos. La nueva técnica de enmallado se utilizó para evaluar la función de un retorno hacia atrás en una cámara progresivamente sellada y otra cámara ventilada por canales. [ABSTRACT FROM AUTHOR] |
