Abstract

The purpose of this work was to develop and conduct a full factorial experiment to determine the temperature of fire in cable tunnels with different sizes, aerodynamic parameters and fire load.

In the previous work, three independent factors were established: the cross-sectional area of the cable tunnel, the fire load, and the horizontal component of air movement inside the tunnel. determined that in order to build a mathematical model of the temperature regime of a fire in a cable tunnel, a full factorial computational experiment must be performed.

Eight numerical experiments were conducted according to the design matrix developed during the research. To determine the baseline data for the full factor experiment, eight computer models were calculated that included the maximum and minimum interval options in different combinations.

The results of the study obtained regressions of the maximum temperature inside the cable tunnel during the fire, the duration of the fire in the designated local area of the cable tunnel, and the time of reaching the maximum temperature inside the cable tunnel during the fire.

In this work, further development of the use of computational experiments to determine the temperature of fire under different conditions was further developed. The temperature modes of fire in cable tunnels with different sizes, aerodynamic parameters and fire load, as well as the dependence of the temperature of the fire on these parameters are also determined.
