Study on suppression of bituminous coal explosion by inert powder in cylindrical space

Case Studies in Thermal Engineering
In order to understand how to control the spread of bituminous coal explosion, a cylindrical explosion tube is used for research. The results indicate that within 60 ms, the flame develops to the top of the tube.
