Abstract
Experimental investigation of gas dispersion in a critical infrastructure area was performed using a boundary layer wind tunnel. The dispersion of gases is evaluated from the point of view on required function of security systems in case of critical infrastructure accident involving airplane attack. Physical model of the critical infrastructure installed in the wind tunnel is subjected to measurement of gas concentration with flame ionisation detectors.
Highlights
Critical infrastructures, such as power plants, are fundamental part of state infrastructure and must provide power for the other necessary parts to function properly
This paper describes modelling of gas dispersion in an area of the critical infrastructure facility in case of a large aircraft impact
2.3 Flow and dispersion measurements The flow field of the incoming boundary layer was measured with single-sensor hot-wire probe and the concentration at desired points was measured with flame ionization detector (FID)
Summary
Critical infrastructures, such as power plants, are fundamental part of state infrastructure and must provide power for the other necessary parts to function properly. The power plants might be vulnerable to terrorist attacks or accidents using large aircrafts, i. This paper describes modelling of gas dispersion in an area of the critical infrastructure facility in case of a large aircraft impact. The fire and smoke dispersion of burning jet fuel in the vicinity of critical infrastructure buildings will be evaluated in a computational model. The fire and smoke dispersion will be evaluated from the point of view on required function of security systems in case of critical infrastructure accident involving intentional airplane attack. The physical modelling of the dispersion inside critical infrastructure area will serve for validation and comparison with the computational model. The safety of nuclear power plants against aircraft attack was studied e.g. in [6]. The model is depicted in Figure 1; main flow direction is from right to the left
