Abstract
In this study, a mathematical model for investigation the effects of internal heat losses on the flame speed and temperature profile in Aluminum Particle Clouds combustion with continues reaction rate have been studied. The present study extended previous results by bridging the theories of the non-adiabatic stationary dust flame and the propagation of premixed flames in one-dimensional channels accounting for heat-losses to particles and environment. The results showed that the effects of heat losses played an important role in flame regimes and flame transition. Furthermore, it was found that convective heat losses significantly decreased the velocity of flame propagation and temperature in post-flame zone. Comparisons between the analytical solutions and the experiment results showed a good agreement.
