Summary on Grant Application Form |
|
A hierarchy of mathematical models, complemented by physical experiment, will be investigated by a combination of analytical methods, based on a dynamical system approach, to determine and quantify in what circumstances combustion fronts may develop from a hot spot within a reactive material. The main conditions to be considered are (a) when the decomposition process of the material is itself exothermic, (b) the exothermic process is oxygen supply dependent, and (r) there is a mitigating effect either of material loss or the creation of a cavity as a result of gaseous product formation. Experimental measurements will be made on materials (such as charcoal or cellulosics) contained in a wire mesh basket (<10cm), and in which a small electrical heater is buried. Power dissipation and thermal responses will be measured. Links are to be established also with experimentalists who study the effect of transient power inputs to reactive media. The ultimate objective will be the development of power inputs to reactive media. The ultimate objective will be the development of practical measures of safe operation or for early warning of dangerous behaviour. These measures will involve the material properties and geometry, source parameters and, where necessary, the character of transient behaviour.
