THERMAL RADIATION EFFECTS ON THE COMBUSTION BEHAVIOR OF POROUS CHAR PARTICLES

Abstract

The effects of thermal radiation on the pseudosteady state and transient behavior of porous char particles exposed to an oxygen containing environment are investigated. The numerical simulation results show that particles that do not interchange radiant energy with their environment are characterized by wider ambient temperature regions where multiple steady states exist, higher combustion rates, and lower burning times
