“…Pyrosim is a field simulation software, the numerical simulation of fire is based on the principle of Large Eddy Simulation (LES) and follows the basic theory of fluid dynamics (CFD), focusing on the process of calculating the smoke flow and heat transfer under the fire break out scenario 11 . The basic solution equations for the smoke flow, velocity field, temperature field, and concentration field in the simulation are described as follows 2 . Conservation of mass equation where, ρ is the density, kg/m 3 ; t is the time, s; is the velocity vector, m/s; ∇is the Hamiltonian operator.…”

“…Therefore, scholars have studied mall fires and personnel evacuation mainly in terms of smoke prevention measures, path planning, and access problems. In terms of smoke control measures, Shoshe et al 2 used FDS software to simulate and compare shopping centers with and without air curtains installed at key locations. It was observed that when the air curtain jets were discharged at 10 m/s, about 37% of the fire-generated heat was confined to the fire source storage reservoir.…”

“…На теперішній час основними нормативними документами, які регулюють вимоги в сфері пожежної безпеки торговельно-розважальних закладів, є: ДБН В. В роботі [4] було досліджено статистику пожеж в Бангладеш, де зазначено, що протягом 20 років кількість пожеж зросла в 5 разів, і принаймні 4057 пожеж в 2019 році були пов'язані з торговими центрами та ринками, що становить орієнтовно 17% від загальної кількості пожеж у тому ж році. Автор роботи зазначає, що основною проблемою, яка призводить до збільшення кількості пожеж, є те, що лише 3,6% торгових центрів у країні відповідають необхідним стандартам пожежної безпеки, тоді як 56,1% та 40,3% торгових центрів були оцінені як "ризиковані" та "дуже ризиковані" відповідно.…”

“…Implementation of air curtain will cause separation of two environments without restricting the opening access of these environments [18]. The sealing of cold storage room entrances [19], the apertures of refrigerator display cabinets [20], and smoke confinement [21] are the common applications of air curtains in pollution management. Instead of taking up as much room as vestibules and obstructing traffic, air curtains limit infiltration.…”
