| الوصف: | The oxidation process occurring in a coal stockpile is a serious economic and safety problem. In this research, heat and fluid flow within and around a heat generating porous material (coal stockpile) are numerically investigated by both a FORTRAN code and the commercially available software CFD-ACE for a self-heating medium. Transient variation of the maximum temperature inside the coal stockpile, as the main parameter to study self-heating and spontaneous self-ignition is monitored and a threshold is presented. It is shown that the maximum temperature inside the pile may reduce/increase depending on the stockpile average porosity and permeability. |
