Modeling smoke removal processes in underground transport destination structures
The issues of life support and safety of a person located in underground structures have always been of paramount importance when designing such facilities. In particular, this applies to underground structures for transport purposes, namely motor transport tunnels and underground parking lots, where people are expected to stay. In this case, the main risk factors are the emission of harmful substances during engine operation and the possibility of smoke pollution by toxic combustion products in the event of a fire in a closed underground space. It is the value of the design fire load that determines choosing the parameters of the ventilation and smoke removal system. The article presents mathematical models for engineering calculations of longitudinal smoke exhaust systems in motor transport tunnels and underground parking lots.
