CHANGES IN CABLE TUNNEL COMPARTMENTS IN THE PROCESS OF RECIRCULATION OF BURNING PRODUCTS FOR FIRE EXTINGUISHING APPLICATION

Abstract

The mathematical model of heat transference process in tunnel compartment and pipeline in case of cables burning after its suspension in recirculation period of fire gases is represented. The prognosis of heat regulations in compartment recirculation outline and pipeline depending on the recession of subsidiary ventilator and recirculation duration is made.
