Cfd Analysis Of Mine Fire Smoke Spread And Reverse Flow Conditions, J. C. Edwards, C. C. Hwang
Cfd Analysis Of Mine Fire Smoke Spread And Reverse Flow Conditions, J. C. Edwards, C. C. Hwang
U.S. Mine Ventilation Symposium
A Computational Fluid Dynamics (CFD) program was used to model buoyancy induced Product-Of-Combustion (POC) spread from experimental fires in the National Institute For Occupational Safety And Health (NIOSH), Pittsburgh Research Laboratory (PRL), safety research coal mine. In one application, the CFD program was used to predict spread from fires in an entry under zero airflow conditions. At a location, 0.41 m below the entry's roof at a distance of 30 m from the fire, the measured smoke spread rates were 0.093 and 0.23 m/s for a 30 and a 296 kw fire, respectively. The CFD program predicted spread rates of …
