This paper investigates smoke movement and its stratification in a lay-by of a 900 m long
road tunnel by computer simulation using Fire Dynamics Simulator. The lay-by is located …

The efficiency of tunnel ventilation systems is commonly evaluated through numerical
modelling. In this survey, two CFD models were developed by means of Fire Dynamic …

This paper presents two designs of the axial reversible jet fan, with the special focus on the
impeller. The intention was to develop a reversible axial jet fan which operates in the same …

Road tunnels are equipped with various safety installations that enable the tunnel's
autonomous response to fire in order to ensure conditions suitable for safe self-rescue and …

The large amount of computing resources required for the simulation of complex natural
processes demands a thorough analysis of the efficiency of the calculations and the …

Tunnel lay-by spacing is directly related to traffic safety and engineering investment.
Nevertheless, its mechanism is not clear, and the rationality of the exiting norms with respect …

Heat strain is a serious health issue in many manufacturing industries, including steel plants,
foundries, and automobile industries. This research attempts to control the high …
