A theoretical approach for prediction of temperature and heat flux of copper beads on wood surfaces.

The present research is dedicated to investigating the fire hazard risks of molten metal particles from electrical wires or devices, in enclosed places (houses, factories, etc.). A mathematical model is proposed for the calculation of the temperature of the molten particles as well as the heat flux they can transfer to the attached surface and the temperature of the attached surface. It is concluded that the probability of fire ignition for a specific bed is a function of the molten particles' diameter and the ratio of the contact to total surface. The proposed model can be used for fire investigation analysis in indoor places due to potential electric faults. [ABSTRACT FROM AUTHOR]
