Abstract

Purpose. The paper is devoted to analysis of experimental study and evaluation of the influence of the horizontal opening on the temperature of the fire in the compartment. The limitations of the previous scientific results in modeling fires are shown.

Methods. Compartment having both vertical and horizontal openings. To analyze the difference in fire temperature in the compartment Fire Dynamic Simulator has been used.

Findings. An analysis of literature sources and modeling of wood burning in an administrative compartment for evaluating the influence of the horizontal opening on the temperature of the fire in the compartment. A significant effect of ventilation through horizontal openings on the fire temperature is detected. Modification of the algorithm used in the development of the calculation methodology is suggested.

Application field of research. The results can be applied in calculating the compartment fire temperature taking into account the horizontal openings.

Conclusions. Horizontal openings have a significant influence on the fire temperature and should not be ignored during the calculation. It is necessary to revise the calculation algorithm used in the STB 11.05.03 methodology.
