Summary on Grant Application Form
The central objective of the proposal is the development and critical appraisal of a range of mathematical models which represent the physico-chemi interactions of low temperature hydrocarbon ( cool flame ) combustion in various physical and gravitational environments. These models will be designed and used to address the specific objectives: (i) set up a reduced thermochemical model that captures the key kinetic features of alkane oxidation when the mass and energy conservation are coupled by diffusive fluxes in an axisymmetric closed system, consistent with a zero gravity idealisation (ii) map the response to changes in control temperature and initial concentrations, investigate spatial patterns arising from the chainthermal feedback in the system, study the dependence on diffusion coefficients and Lewis number, and compare numerical results with those from tt KC 135 microgravity flight experimental programme (NASA), (iii) adapt the model for asymmetric initial boundary conditions (as pertains experiments for admission of reactants to the vessel) and develop appropriate codes for two spatial dimensions so that optional modes of heat and mass transport may be invoked. (iv) modify the physical model to accommodate convection and buoyancy and explore how increases of Rayleigh number modify the behaviour, first related to microgravity (KC135) and then with respect to terrestrial studies, (v) address the performance of the kinetic models with particular reference to propane and butane oxidation using terrestrial results for validation, so that predictions for the NASA International Space Station (ISS) zero gravity programme may be made.
