Studies on Motion and Thermal Behaviors of Fire Products through Full Scale Corridor (Part III) Analytical Study on Decreasing Modes of Velocity, Excess Temperature and Gas Concentration along Corridor-direction

Abstract

This paper describes an analytical approach to the evaluation of decreasing modes of average velocity, average excess temperature, and average gas concentration with distance along the full scale corridor based on the experimental data. Discharged mass flux and entrained mass flux through the free surface were estimated based on the gas concentration. The analogical relation was also estimated between the decreasing modes of average velocity and average excess temperature for corridor-direction.
