Obiettivo
"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 two-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:
-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;
-Develop/implement a two-way coupling approach through which the influence of the mist droplets on the flow can be classified;
-Develop a phase transition model for the mist formation and couple the model with an existing LES code;
-Validate the model for the predictions of fire suppression and extinction effect of nanomist with published experimental data;
-Validate the model for simulating the mitigation effect of nanomist on gas and dust explosions;
-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 knowledge for much wider objective.
