Numerical Simulation of Flame-induced Aerodynamics in a Coal Mine Passageway, Semi-empirical Model.
NTIS: PB 240 843 :27 pages
This Bureau of Mines report is concerned with a theoretical study of the aerodynamic response of a single mine entry to flame-induced disturbance. The unsteady, one-dimensional, compressible flow equations were solved using the method of characteristics. This study was primarily undertaken to determine the feasibility of extending the method of characteristics to study the aerodynamic response of complex mine networks. It was demonstrated that although the technique has merit in studying the complex wave interaction in single entries, it appears to be too unwieldly and too expensive for network analysis. Effort was also directed at a further study of the dispersion and filtering characteristic of aerodynamic disturbances in mine passageways.
