In this study, a vertical shaft is coated using silver nanowires (AgNWs) together with reduced graphene oxide (rGO) via the supersonic spray-coating technique to enhance the absorption of solar radiative heat for use in solar air heaters. The rGO/AgN

In this study, a numerical analysis was conducted on the factors affecting evacuation when fires occur in multi-family houses. The parameters of fire size, growth rate, and location, as well as open or closed corridor-window conditions were considere

In recent years, it has been observed that when a fire occurs in a multi-use facility, a toxic fire smoke rapidly rises through the vertical shaft and spreads due to the chimney effect and hot buoyancy. Generally, the fire smoke spreads rapidly throu

The vulnerabilities of high-rise buildings to fires and the safe evacuation of the occupants therein have been consistently highlighted in the media. Unexpected natural disasters that occur frequently such as earthquakes increase the potential risk i

Smoke rise in elevator shafts and stairwells is a primary risk from fires. Information on temperature and smoke velocity is necessary for safety evaluation and evacuation guidelines when designing high-rise buildings. Small-scale experiments were per

Smoke kills more people than the associated fire and thus predicting smoke spreading inside high-rise buildings is of paramount importance to structural and safety engineers. Here, the velocity, temperature, and concentration fields in large-scale tu

Herein, we discuss the fundamental aspects of the deflagration-to-detonation transition (DDT) phenomenon in the framework of the analytical theory. This semi-empirical approach facilitates prediction of the pressure rise and the shock wave speed for
