Final Activity Report Summary - NANOMIST (Nanomist for fire suppression and explosion mitigation)

Numerical models were developed and validated for simulating the interaction between fine watermist and fire and propagating flames in explosions. The models were applied to predict the distribution characteristics of micromist in both fully and semi-enclosed enclosures. The model applications examined the interaction between propagating flames in explosions and the micromist. Additional applications, elaborated together with the industrial partner British petroleum (BP), focused on the effect of watermist on fire suppression in offshore environment. Several case studies were conducted to examine the effect of droplet sizes, wind and application rates. A literature survey was also performed on experimental work of watermist for fire suppression. The work led to the donation of a micromist generator from BP to the UK host, which was set up with the view to expand the host's work on numerical modelling to the experimental testing of micromist for fire suppression and explosion control.

Project objective

NanoMist is the trade name for the proprietary process technology of producing, scaling, transporting, and delivering nano- to micron-sized droplets, particles and mists. These technologies can be used to produce ultra fine water mist systems for fire suppression and explosion control and serve as an environmental friendly replacement of Halon 1301. The proposal aims to carry out numerical investigations of the dynamic âStwo-way❠interaction of ultra fine water mist droplets with flames in the context of fire suppression and explosion control. In particular the following four aspects will be investigated: (i) gas-phase cooling, (ii) oxygen depletion/dilution and (iii) surface cooling (likely to be negligible due to the ultra fine size) and (iv) the attenuation of thermal radiation. Both the Eulerin-Lagrangian and Eulerin-Eulerin approaches will be considered within the frame of an existing large eddy simulation (LES) code. The key objectives of the project includes: Â-Develop/implement SGS combustion models that will facilitate the investigation of the dynamic interaction between ultra fine water mist with fires and propagating flames which would otherwise lead to explosions. Â-Develop/implement a âStwo-way❠coupling approach through which the influence of the mist droplets on the flow can be classified. Â-Develop a phase transition model for the mist formation and couple the model with an existing LES code. Â-Validate the model for the predictions of fire suppression and extinction effect of nanomist with published experimental data. Â-Validate the model for simulating the mitigation effect of nanomist on gas and dust explosions. Â-Establish a sustainable research programme with international collaboration on ultra fine watermist for fire suppression and explosion control during the return phase. The research is multi-disciplinary. It calls for the integration of many otherwise disparate specialisms and will provide knowled..."
