Abstract:

 

There is growing evidence for influence of irradiative  heat-flux in the large scale confined fires onto the fire growth rate  and subsequently there is a need to understand mentioned relationship  regarding the development of the effective fire-suppression methods.   In this study, the influence of the traffic tunnel's curvature onto  the consequences of the fire on both the will be investigated.  Heat  radiation of the flame and the gaseous products of such non premixed  combustion (NPC) depend on the geometrical position of the inflammable  objects as well as on the propagation of the gaseous combustion  products in such type of enclosure.  In a traffic tunnel the position  of the inflammable objects alone will determine the development of  this large scale NPC, during this planed investigation.  The  simulations based on computer fluid dynamics (CFD) with characteristic  conditions - real-geometry factors - will be performed.  This investigation; for the given geometrical characteristics of the  investigated operating road tunnel; will establish an important  crosstalk between the large-scale confined combustion of inflammable  hydro-carbons and its propagation in an curved underground traffic  facility.
