Review of common fire ventilation methods and Computational Fluid Dynamics simulation of exhaust ventilation during a fire event in Velodrome as case study

Abstract

The main purpose of fire engineering design is to ensure human safety in the situations of fire in buildings, car parks and tunnels. Toxic gases and carbon monoxide induced by fire get the life of many fire victims, hence, fire safety elements like velocity, heat and smoke dynamics have been focused by many researchers to facilitate safe exit in the case of fire. The goal of this paper is to review the fire ventilation methods in fire safety and measurement methods used as the performance of ventilation systems. Managing the smoke in case of fire can reduce the carbon monoxide that poses the deadliest risk to people. Thus, the control and removal of gases and smoke in the case of fire is crucial in human safety and saving a property. In addition, this paper conducts a case study on smoke propagation and removal of smoke from Velodrome environment in which fire occurred. To conduct this case study, Computational Fluid Dynamics (CFD) simulation of exhaust ventilation system for managing smoke in building's environmental called Velodrome has been developed. The results were investigated and analysed in 3-dimensional plane. The results of these CFD simulations show that the source of fire can be removed by activating exhaust system, and thus, the risk of fire victims' s life and damaged property can be reduced.

Reversal Ventilation as a Method of Fire Hazard Mitigation in the Mines

“…Therefore, there was a need to find a safe solution for such a case. Nowadays studies on mine ventilation network are being conducted into different aspects: field measurements and numerical evaluation [20,21], optimization of mine ventilation fan speeds [22], improving of present network methods [23,24] and risk estimation for automated ventilation systems [25]. The studies do not include reversal ventilation network analysis when gas hazard is present.…”
