Critical Conditions for the Ignition of a Gel Fuel under Different Heating Schemes

A model was developed to research the critical conditions and time characteristics of ignition gel fuels in course conductive, convective, radiant mixed heat transfer. MATLAB used for numerical modeling. Original code established pursuant mathematical model. For fuel at initial temperatures corresponding cryogenic storage with different heating schemes, a analysis interconnected processes mass transfer chemical reaction exothermic endothermic phase transitions conducted. The tested by comparing theoretical results experimental data. Dependencies were between key process characteristic (i.e., delay time) ambient temperature when following parameters varied: emissivity, emission coefficient, activation energy pre-exponential factor vapor oxidation reaction. values main source determined. these values, consistently realized each scheme. fluxes necessary sufficient typical
