Automatische Brandbekämpfungsanlagen in untertägigen Bauwerken

Abstract

AbstractA fire can occur in many areas of a transport system. Detecting fires at an early stage and rapid automated fire‐fighting can significantly minimize or completely prevent damage to rolling stock and infrastructure. In addition to effective fire‐fighting, people should be safeguarded, the systems should be economical, and activation should cause a minimum of damage. Despite the positive effects of using automatic fire‐fighting systems in terms of building protection and reducing the fire load, there may be negative effects on escaping persons during the escape phase. Different systems such as the high‐pressure water mist system and the deluge system are investigated by CFD simulation and evaluated with regard to their use during the escape and external rescue phases.
